The battery for the "Notstromausfall" needs to be exchanged. C.Holz ordered already new ones and will exchange them as soon as they are delivered. 

Moin Sascha,

wie telefonisch besprochen, am Montag früh braucht MID He 5.0. Es sind fünf flaschen beim Gasenlager (nahe Guesthouse) und zwei bei den Stickstoffgitter. Es müssten vielleicht/eventuell (je nach dem was für Experimentzwecke/Experimentverbrauch) alle 2 Stunden welche eingebaut/ausgetauscht in deren Gasschrank. 

Ulrike (sie hat am Montag Frühschicht)  bzw. MID Kollegen werden dir den Druckminderer im Schrank zeigen. Inzwischen sie wird SRP (Vasilii) kontaktieren, dass sie eine Einweisung/Safety vorziehen um später das Flaschenwechsel selbst machen zu können (ab der Zeitpunkt wann Safety gemacht ist/wenn du Feierabend hast, in deren Spät- und Nachtschicht) 

Mehr wirst du am Montag erfahren. 

Lorenz rief um 12:18 an und teilte mit, dass Peter sich bei ihn meldete und zwar auch Peter hätte/kann den Druck nicht höher stellen, es geht nicht. Also bleibt die Flaschenlösung.

LG,

Orkidia

Near the SCS Clean Tent, where the big chamber is, below, on the pump there is a control monitor/display. It peeps and perhpas there is something with that.

Filled two LN2 dewars for the Vacuum group.

Filled LN2 Dewar #25580 for SEC (E. Round).

From the fume hood of the SEC solvents supply, an acoustic warning signal is activated.

Wrote Vasilii B. about this, and he will take care of it.

Jayanath Koliyadu - SPB/SFX wants to store in Ütersen  another Optical Table, QR 48796. It is currently located in the experiment hall near the xhcrew hutch.

Put in the cabinets all the pallet consumables (Gewindestifte, U-Scheiben, Senkschrauben) that O. Smith brought today in the hall.

Again oil drips from the detector lab down into the the experiment hall in the SCS assembly area (near the clean tent). On 15.05 the problem was solved, still the oil drips again. Contacted DET OCD (N. Duarte), who checked in the lab upstairs, but did not have access to another room there.

 According to N. Duarte, so far it looks good, and in the 14:00 shift, D. Lomidze will check the other room and will give/update more information.

Both doors of the MID optics hutch show a blinking orange light (see video below).

On Monday will ask TS if all is fine.

The communication with D. Lomidze (DET) concerning the Si Oil dripping from the ceiling (pic.).

Discussed, labelled and wrapped the parts for SCS which will be transported on Monday to Üttersen.

All of them have a QR code.

Co-Workers: L. Le Guyader, S. Menzel, O. Bilani

Filled (15.-16.06) the drawers with all the M5 screws and M6 upt to M6x60. Rest to continue.

An acoustic warning at HED near room A.22 (rack room). Attached a short video in which the acoustic warning signal can be heard (the other video was too large to upload)

Callled the PRC colleague, who informed HED. Up to now no Feedback.

Filled dewar  #36168 for Vacuum.

Filled dewar #25283 for L. Batchelor. He needed it to XHE2, and O. Smith transported it there.

-> Transport a box with parts  of the Mechanical Engineering group. This will be needed always during the maintenance periods.

-> Structured Block 10

Co-workers: O. Bilani; H. Heuer

SXP had a leaking issue from their ventile (Hahn). It couldn't be exchanged so quick, since they had to order a new one. P. Schmidt sugessted that a dewar with "Schlauch" should solve in a short time the problem. Thus the two dewars filled by P. Schmidt on Monday, are not needed any more.

Filled one dewar with "Schlauch" for SXP.

Co-Workers: O. Bilani; P. Schmidt

-> Connected the dewar in the exp. hutch.

-> Emptied a (more or less broken) table located in the experiment hall (at their small assembly area) and disposed it.

-> Prepared (Anschlagen") a chamber for craning, which s. Arslan will carry out tomorrow.

Co-Workers: O. Bilani, V. Vardanyan

Filled  LN2 Dewar #25576 for SXP.
