Fixed, e744, Mon Jun 4 18:45:15 2018, shumpei, MUST2, Hardware, N/A, No data for two CsIs of MUST2 
|
During E744 experiment, two CsI crystals (number 1 & 10) of MM2 had no data as attached.
When the M2C chamber was opened today, I found at least connection for CsI number 1 of MM2 has a problem.
It takes some time to fix the connection for CsI, so it may be going to be fixed after some hardware problems are found in this week. |

The 8 MUST2 telescopes have been installed and pluged in final configuration. Energy signal have been tested with 2 3-alphas sources, one in front of T5-T6
and one in front of the others.
Energy signal for all telescopes looks ok exept for telescopes 5. Concidering their position with respect to the source T5 and T6 should have the same |

8MeV alpha source image on the target was reconstructed from T5&T6 hit position and target position information.
The target is something like 2 cm diameter collimator.
Now the center of the image is a little bit close to T6(bottom) maybe because the center of the target is placed to bottom side at room temperature since |
