Tue May 25 07:51:48 2021, Jan, Accelerator, ESR stacking cycle length, 2021
|
The full cycle length of ESR with 30 stacks is about 7:45 minutes, out of which 15.5 sec are with target switched ON.
This is without CMB/HTD in parallel. |
|
Tue May 25 08:36:15 2021, Jan, General, lessons learned, 2021
|
1. before using stoch. cooling in ESR, boot and update the windows PC
2. better diagnostics for low energy/intensity beam-target overlapp in ESR is needed (either a clever analysis or a new detector)
more to come |

The two attached plots show the collected Si data up to run0115.
Within this ~15h we have about ~70 counts in the peak region.
This translates to ~4.5 counts per hour.
And shall be compared to the 1 count/hour we had last year. |
