Anastasia + Iulian | ONLINE | General | CD2 | Run 346 | Run 346 still running.
We see in the Must2 impact also the other two telescopes T6T7
and clearly the elastic in the E/Theta
The efficiency of CATS 1 seems a bit lower than previously(see scalers below) |

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, Laurent, Shumpei | MUST2 | Hardware | | M2C vacuum test | We mounted 2 dry pump on the chamber and started pumping at 11h.
Pressure was about 6e-1 mbar around 11h45.
Waiting to switch on the turbo at 1e-1 mbar.
Gailor switch on the turbo during lunch time. We reach 2e-5 mbar, but the vacuum is oscillating. Gailor suspect the gauge.
We added a second gauge, it gave 2E-4, switch to a third one, same reading.
So first gauge to be changed.
we are gradually improving vacuum so we thinks it is plastic releasing gas.
Cooling switch on to -10, blocks are cooling down successfully.
All DSSD, CsI and SiLi works with rather low current (below 0.5uA).
After three day, vacuum level rise to 6 mbar. According to Vincent; this is standard for static vacuum, so no sign of major leak. |

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. |

Adrien Valérian Louis | MUST2 | Hardware | 3-alpha | RUN Source 4 Alpha | run 1: 4 alpha source, without heat shield, 1 bar air inside the target cell.
Data has been taken with a 4 alpha source: 3 alpha around 5Mev plus one around 8.7MeV
On telescope 7 and 8, one can see the four alpha which are not intercepted by the heat shield. Telescope 1 to 4 see only one alpha around 2.5Mev on the border of the strips. T5 and T6 see the alpha at 2.5Mev in the center of stripX.

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. |
