- Switch to tilted data taking with the two LBNL RD53a
- More cosmic telescope data with separate cosmicGui partition
Activities
9:30 AM Sanha called the beam control room to start the beam. There is a water leakage in the klystrons, and the repair/replacement will take 3-4 hours. Test beam data taking will be postponed until the repair/replacement is complete (probably in the early afternoon).
9:50 AM cosmicRun 051. Testing the current telescope configuration for any random noises. Cyclic trigger set to 100Hz. Almost no random noise is seen after 100s.
11:50 Beam is back on (earlier than expected!)
11:52 Started data taking
12:35 Channel 10 beam trigger disappeared. Reason unknown
13:05 Swapping the trigger channels 10 (originally feeding the EUDET) and 11 (originally feeding the cosmic telescope). The original trigger settings are: width 200ns, delay -110488ns for channel 10 (EUDET) and width 100ns, delay -104500ns for channel 11 (cosmic telescope).
| Run | Start | End time | #events | RD53a DUT | Particle rate | Comments |
|---|---|---|---|---|---|---|
| 481 | 11:52 | 11:56 | 1k | C, D | RD 53A tilted at 11.8 degrees. Run ended early to change YARR config. | |
| 482 | 11:56 | 12:35 | 7k | C, D | 4.8 / 0.8 | The trigger from the machine stopped. Run ended. |
| Cosmic Run | Start | End time | #events | Trigger Delay | Comments |
|---|---|---|---|---|---|
| 051 | ~9:50 | ~9:51 | 1k | -104500, 224 | Testing without the beam for random noises. No significant noise seen. |
| 053 | 11:56 | 12:27 | 10k | -104500, 224 | |
| 054 | 12:34 | 13:05 | 9k | - | Cosmic run ended in order to change the trigger over to the RD 53A's |
