Post on behalf of Harald Sinn
Fortschritte, die ich letzte Woche beobachten konnte, sind:
1.) Die Spiegelkammern wurden weiter lokal getestet. Benoit hat gestern abend den
letzten Encoder am XTD9 vercrimmt. Wahrscheinlich muss der dann noch mal getestet werden,
aber dann sollte das abgeschlossen sein.
2.) Gestern haben wir zusammen mit Jan Tolkiehn den SRA und Filterkammer getetstet.
SRA ist OK (incl. der Encoder), die Filterkammer auch, aber Wolfgang meinte, er müsste die
LImit.switches noch mal etwas nachstellen (dafür sollte dann aber Karabo funktionieren, s.u.)
3.) Die PBLMs in XTD2 und die letzten beiden in XTD9 sich verkabelt und könnten von uns aus lokal
getestet werden. Jan meinte allerdings, dass an den Elmo/technosoft (PBLM hat Elmo) Treibern noch etwas Arbeit
nötig ist, um zuverlässig Tests zu machen (MCI Library)
4.) Andreas Block hat mit Maik Neumann ausgemacht, dass sie sich Montag treffen und alle fehlenden Wasserverbindungen in
SASE1 durchgehen und am besten sofort machen,.
5.) Makus Schlösser hat bestätigt, dass nächste Woche (wohl leider nur) ein Team für uns arbeiten kann.
Das wird zunächst aber in SASE3 hinten anfangen, weil wir da schnon einen Arbeitsstau in der Vakuumgruppe
aufgebaut haben. Die relativ wenigen Komponenten in SASE1 werden natürlich auch fertig, aber Markus meinte, er würde vorhar
lieber noch einige Daten konsolidieren.
Zum lokalen testen: Das ist schon sehr wichtig, allerdings sollte es noch nicht mit dem technical commissioing
verwechselt werden. Beim lokalen Testen wird nur festgestellt, ob sich der Motor in die richtige Richtung dreht
und ob am Terminal die richtige LED leuchtet, wenn man den entsprechenden Endschalter drückt
(Jan weiss dann, welche LED leuchten muss). Man sollte aber z.B. nicht auf den Endschalter fahren, weil in diesem
Modus kein automatischer Stopp stattfindet, sondern man muss manuell eine Stopp Taste drücken.
Auch werden nicht Motorgeschwindigkeit etc. optimiert oder gespeichert.
Deswegen ist es wichtig, dass wir möglichst schnell Beckhoff+Karabo zum Laufen bringen, weil diese Tests
essentiell sind und von den Komponentenverantwortlichen gemacht werden müssen.
Falls die MCI Library tatsächlich ein Problem darstellt, was etwas dauert, würde ich vorschagen, die
Beckhoff Motion Loop jetzt schon in Betrieb zu nehmen, mit den Motoren, die wir getestet haben.
Grüße

Status of Differential Pumping, posted by Tobias Haas on 09 Feb 2017, 17:16

Post on behalf of R. Villanueva
please find attached the updated status of the Differential Pumping
Modules in SASE 1. Just a few comments.
1. As you can imagine, no progress after KW4 in XTD2: system is ready to
deploy Karabo.
2. In XTD9, we have been pushing forward to finish the local test with AE.
Right now, everything has passed the local test except 3 vacuum gauges
that will be rechecked after the meeting. The main reasons for the little
progress (84%----->87%) are:
a) more problems than expected with the cabling.
b) a faulty Beckhoff Terminal.
c) prioritization of manpower (AE and VG) in other devices in the
tunnel.
d)....the usual "sigmoidal" behavior of this kind of process.... ;)
3. In any case we aim to leave the system ready tomorrow so next week the
interlock code can be deployed safely.
Have a nice evening,
R. |

Update WP74 cabling status (w5), posted by Jan Grünert on 03 Feb 2017, 08:48
|
Information posted on behalf of Torben Falk (WP74 cabling)
Wir haben nun alle Kabel für den XGM in XTD2 am Beckhoff angeschlossen.
Alle Leitungen sind bereit zum einstecken in die jeweiligen Komponenten.
Es sind alle "valve connection boxes" angeschlossen, bis auf eine. Da besteht noch klärungsbedarf mit Florian. (ist aber auch schon am Beckhoff angeschlossen, nur device-seitig noch nicht)
Dementsprechend wäre der lokale Beckhoff Test möglich.
Ich habe mit Tobias Freyermuth geredet und der hat für den lokalen Beckhoff Test leider erst mitte / ende nächster Woche zeit..
Außerdem haben wir in XTD9 Kabel für den HiREX gewechselt. Da waren ein paar Kabel zu kurz. Die haben wir nun mit passenden ersetzt.
Andreas hat sich für die Timing verkabelung um die nötigen Kabel / Material gekümmert, die gebrauchten Längen habe ich ausgemessen und ihm zukommen lassen. Das Material soll Anfang nächster Woche da sein.

WP74 components in XTD2 - electrical connections, posted by Bernard Baranasic on 02 Feb 2017, 18:29
|
Status of WP74 components testing and wiring this week:
On Monday we tested SR Imager and K-Mono:
- issue with motor connect pinouts was discovered and I wanted to correct pinout today, but K-Mono and SR imager motor connectors are Lemo with soldering pins, which make pin changing more difficult than crimp version...
- this is still not done (we can exchange all connectors to crimp version or temporary change pins on crate side).
This week done:
- connected SR imager EPS switch (on the imager - not yet in the crate)
- On XGM Gas Panel is installed new HUBA gauge, and I connected it to the crate (now everything from Gas Panel is connected to Beckhoff terminals in WP73_VAC crate - Rack 1.3).
- FEL imager - EPS switch is connected properly, but Digital Input terminal in WP73 EPS crate - Rack 1.5 is defect (doesn't work at all).
- I placed cable for EPS switches of MCP detector, but not placed in the Rack (Rack needs to be opened - Roxtec feedthrough is closed)
To be done:
- K-Mono - switch pins 1 and 2 on Motor connectors (Y-1, Y2 and X).
- SR imager - switch pins 1 and 2, and switch pins 7 and 8 on all Motor connectors.
- SR imager - EPS switch connect from WP74 crate to WP73_EPS crate (one cable inside crate).
- XGM vacuum to HV crate interlock (inhibit) is still not connected (I am waiting for Beckhoff terminal, but this connection was not tested yet).
- MCP detector - EPS switch cable needs to be laid inside Rack 1.7 (Rack needs to be opened - Roxtec feedthrough is closed).
- MCP detector - vacuum to HV crate interlock (inhibit) needs to be connected - Beckhoff crate is prepared - missing cable from MPOD to Beckhoff terminals. |

XGM resistor issue - analysis progress, posted by Jan Grünert on 01 Feb 2017, 17:42
|
This is the current (w5) progress at DESY concerning the analysis of the serious XGM resistor issue (summary; a detailed report by DESY is available):
- The new “pulser test” was verified at an operational XGMD at FLASH. The test method is (unfortuately) OK. This means that the test results with issues from last week on all our XGMs are REAL.
- 25% of all resistors in XBPMs affected, 0% of resistors in HAMPs affected, no capacitors affected.
- Since no HAMP resistors are damaged, damage by environmental conditions (venting, humidity etc.) can be excluded. The main differences to the affected resistors are the HV-conditioning and the experienced HV-values of the resistors (typically XBPM resisotors are tested up to 12kV, HAMP resistors each see much lower voltages).
- An XGMD chamber at FLASH was tested-to-destruction-of-resistor by applying a large differential voltage (>3kV) between neighboring electrodes, e.g. on mesh_e and FC_e. These resistors (Caddock MS220) have a nominal voltage breakthrough rating of ~500V but never had issues. They are used in all our XGMs.
- New, other resistors (Ohmite MOX-1N-13) with higher voltage breakthrough rating of 10kV were procured and arrived tuesday
- The new resistors were built into the tested-to-destruction XGMD at FLASH, unit is now pumping, will be retested with applying pulsed HV (on both Caddoc and Ohmite resistors) when at suitable pressure.
Further plan (w5end + w6) concerning the XGM resistor issue:
- If the new resistors survive the test, then next monday the XGM01 at HERA-S will be opened, the tested-defect resistors will be checked and replaced with the new resistors.
- If all tests on XGM01 are then ok including an acceptable RGA, all other XGMs (XBPM chambers) will be opened and resistors exchanged. Even ok-tested resitors would be exchanged to avoid future unexpected failures. HAMP chamber resistors will not be exchanged (large number >20 of resistors, no failures).
- If the RGA is not acceptable, the resistor Ohmite MOX-1N-16 is another alternative, but has increased delivery time.

Status of several XTD2 wiring tasks - on behalf of Bernard Baranasic, posted by Jan Grünert on 01 Feb 2017, 17:26

Dear all,
today I connected XGM Gas Supply to Beckhoff terminals in WP73 Vacuum crate in Rack 1.3.
On Gas Panel, HUBA gauge is still not replaced, so it is not connected, I talked to Florian yesterday and give him an idea how we can connect this gauge and other signals for Gebäudeleittechnik (trough wago terminals).
Next step for this crate should be connection to all pump controllers and other vacuum equipment, after this crate should be connected to the tunnel vacuum loop. I assume that Torben and Marc can do this together with AE and Vacuum group, so I didn't take any actions...
Additionally in this crate we should connect Inhibit signal from HV iseg crate, for this we need to add:
Proposal from NC:
"I did not test it, to 'create' a TTL we can use either
es9505+es2624 or es9505+es2124
the only difference is that the ES2124 is short-circuit proof, the ES2624 is not, that means that in this case a Flink fuse ~0.3A-0.5A should be inserted."
- WP74 don't have these terminal here and if we order now it will take some time (I am not sure what to do because we don't have proven connection).
In Rack 1.7 I connected Inhibit connection to WP73 vacuum crate (terminals EL9505 & EL2624), but cable from MPOD crate to Beckhoff crate is still not there. Torben said that he has connectors so I believe he can connect according to electrical drawings (these pages are added to XTD2 MCP drawings on Alfresco)
In Rack 1.5 I tested FEL imager EPS switch and find out that Beckhoff terminal DI (ES1008) is not working (24V is on input, but there is no light on LED, all channels are the same).
EPS switch is removed From FEL imager, and I will reconnect it to Normal Open connection.
Best Regards,

Post on behalf of S. Brockhauser
Since I am in Grenoble and visiting ESRF, I will not be able to give you the report in person. Instead Alessandro can give you a Summary.
In fact:
- we did collect the full list of the Karabo names for all the equipments involved
- we have started our sprint and we are on track
As next things:
- we are collecting all the required Karabo(!) default parameters
- we plan to finish the sprint as planned and presented last time.
Until now we have not experienced and obstacle.
Best wishes

XGM at XTD2 / issue with in-vacuum-resistor, posted by Tobias Haas on 26 Jan 2017, 17:02
|
Post on behalf of Jan Grünert:
during HV-tests on the installed XGMs, our DESY colleagues from Kai Tiedtkes team have found an issue with one of the electrodes / resistors inside one XGM vacuum chamber at XTD2.
Roughly, we know the following:
1) If not repaired, we would lose at least the capability of monitoring shot-to-shot horizontal beam position at this XGM location. This is a lower-priority info.
2) However, it’s not yet fully tested if other functionalities could be affected. In case the absolute calibrated intensity info is affected, then clearly we would have to repair.
3) Since the cause of the resistor-irregularity is not understood, there is a risk to damage the other (operational) remaining resistors in the other chambers of the same XGM.
It is not yet fully clear
a) what is the cause for the irregular behavior (it concerns a resistor inside vacuum which dramatically changed its resistance, which apparently possibly might happen even during a correct dry-nitrogen venting),
b) the entire consequences for operation with this XGM
c) the effort/details of a potential repair (could include up to removing one of the four chambers off the girder out of the tunnel into a lab, certainly needs re-survey)
d) if another XGM chamber is affected (so far tested 2 of 6).
The DESY colleagues are running various tests with us on the XGMs, also extending to all the other XGMs, to get answers to the above questions in order to allow a decision on “repair/not repair”.
Since this concerns the internals of the high-prio XGM in XTD2, we could ask Kai Tiedtke to give us his brief 10min report and recommendation in the tomorrow SASE1Readiness Meeting. Should we request his presence / will you add him to the agenda ?
Best regards,
Jan
