*Vacuum issues: There seems to be a leak in the arm nr. 6 (2.4mm CVD Diamond). This has escalated to trip several times the vacuum sector interlock. VAC will do an intervention to XTD1 with broken interlock tomorrow morning starting 9am to remove arm 6 permanently and putting a blind flange instead.
*We can measure for today with the 2.4mm CVD Diamond inserted into the beam.
*Measurements on Vycor and glass samples with different attenuation at and repetition rate (2.2 and 4.5 MHz)
*A25 trip at 1:14, after some intervention we get the beam back at 2:12 |
