 Thu Aug 31 08:36:34 2023, CB, NEG activation
|
Found CARME at 50C, a bit cooler than expected, probably due to invasive tent changes yesterday to mount missing wires. Increased heaters temperature
to 300C

Run number changed 09:44 - Now run 23
Moving motors with the injection
Ring signal very weird, moving in for short time and staying out for 15+ seconds. |

Fri Oct 8 17:56:35 2021, CB RSS, Motors test
|
Attempted first motor test in XHV. Wired and connected limit switches and string potentiometer.
Set up raspberry pi to control motors (.124). Set up pi for remote headless access.
Moved jumper on Teknic hub from 1 to 2 motors configuration. |

Tue Oct 12 09:22:37 2021, RSS TD + OG DR, Motors problem solved
|
Neg and ion cables were taken off and were put in the box.
Top support was taken off.
Motors are rotating again. Have to be careful with the position of the limit switches. |
|
Mon Sep 6 14:13:17 2021, CB ML, Motors mounted - first attempt
|
Mounted both motors on CARME. Started
with outside motor.

Sun Jun 25 14:30:06 2023, JM, TD, Motors bias test
|
The motors were moved using the pneumatic only, in and out for several cycles to gauge the effect on the vacuum. For the left arm no change in pressure
was observed. For the right arm a small increase of 0.04e-7 mbar was observed which was quickly reduced by the turbo.
The detectors were then biased to see if movement had any effect on the leakage current (large effects were observed in 2021 beamtime). Movement |

Sat Sep 4 15:54:50 2021, CB RSS, Motor mounting preparation
|
Prepared the motors to be mounted and
found all components required. No issues.
May have to partly dismount again to fix

Changed slow comp threshold to 0x32 (500 keV). Checkloaded.

09:10
Arrived at GSI. Leakage currents status same as before, DSSD4 is still fluctuating. DSSD1 and DSSD3 currents are definitely lower again compared
to previous days. I am convinced they are decreasing over time, whether this will be enough for our measurement.... |
