e748 | EXL | General | | Progress On EXL |
We fiddled around with EXL trying to get a reasonnable 60Co spectrum.
We moved the source to the windows flange, so it is now facing the EXL detector with minimal matters inbetween, although rather far away (around 1m).
We set change the hardware gain on the second module, so the last two channels have the same hardware gain than the rest of the detector. This is an hardware gain of 30.
We set the software gain to 0 overall.
We set the software threshold to 15.
A rought estimate made this a 7 MeV range with a 300 keV threshold.
We are taking data (run 15) to check that. |

e748 | RUN | General | 3-alpha | Run 15 |
Run 15 is started.
Source: We have a 3 alpha source in target position and a 60Co on the window flange.

e748 | EXL | Hardware | | Gain changed on EXL |
Run 15 online analysis showed waht we believe was 4 MeV range.
So we change the hardware gain on EXL to 2 on the first module and 5 on the second one (channel 17 and 18).
We changed the software gain to 9 on the first module and 6 on the second module.
We left the threshold to there previous values. |

Adrien Matta, Phil Adsley | MUST2 | General | | MUST2 Dead Time |
We cabled the Dead time in the scaler.
We have a 100Hz pulser (entry 2 of U2M) in coincidence with the DT output of the GMT (entry 1), giving a direct reading of the dead time.
Note on MUST2 dead time:
- Without zero suppression the dead time caused by MUVI is 2ms. So this give a 40% DT at 180 counts per second.
- With zero suppression, the DT fall down to 240us (80us cash in to interrupt the CPU and, 80us to process the signal from MUVI to CAS and 80us to send the parameter back to the back plane). So this give a 5-7% DT with 180 counts per second.
- The ADC works in parallel of MUVI, so the DT are not cumulative. |

e748 | MUST2 | Hardware | | MUST2 SL cable repair |
Three cables came back from ASCO, two of them were the original spare cables.
Report from ASCO:
- The spare could not work because two pins were soldered together, so the spare never worked
- The other one had a broken pin on the fisher side. Try not to twith the cable when rotating the connector to plug it on the flange.

Adrien and Phil | MUST2 | General | | MUST2 telescope test with alpha source |
All Telescope now pass the I2C test.
We ran with an alpha source (attached pictures for the overall sequence),
1. at first the source was at 0deg: T1-4 OK; T6 got half of X strip missing, Y Ok; T7 got half Y missing, X Ok. T5 and 8 see nothing
2. source at 150 deg: T1-4 see nothing; T6-7 see nothing, T8 Ok; T5 got every other strip missing on 3/4 of Y (surely a capton issue).
3. source at 90 deg: T6-7 OK. |

e748 | OTHER | General | | Plan for 23rd of June |
We have to open today, I started warming up of the telescope at 9h18 today.
Once open, we have to check on T5 DSSD capton and fix them.
Surveyor will carry out there measurement in the afternoon.
We plan on closing again this evening to perform alpha calibration over the weekend. |

Adrien, Laurent, Vincent | OTHER | Hardware | | MUST2 chamber opening |
We opened the chamber and the surveyor took there measurement.
We closed the chamber with a 3 alpha source in the target position and a 60Co source on top.
All is now under vacuum, turbo are on and we are already below 1e-4 mbar. Cooling started, right now alcool at 10deg; copper at 12deg.
T5 capton fix.
I will start the LV tonight or tomorrow morning to run pedestal alignment and calibration over the weekend. |

Adrien | MUST2 | General | | Restart |
Chamber at 2e-5, cooling -9deg outside; -5 on copper LV off.
Starting BT and HV. No trip; normal current (1-2ua on DSSD; ~0.01 on CsI, still high current,9ua at 450V SiLi1 T5, other SiLi at 4-5ua).
DAS Config ok, passing I2C.
Start DAQ Ok storage off: all actor working 500kb/s, 200kb/s
GRU start ok; but receive no buffer. Kill all the daq and das, work ok.
Alpha look nice on all telescope that see the source (1-4 and half of 6/7).
All good for tonigh. let it run with storage off, waiting for the temp to set in before calibration. |
