|
Today we found different problems, no time on T4 and no signal on T5 and T6 CsI tripping. After changing cables and a lot of tests with the chamber open
and only the BT ON, T4 and T5 problems seemed to be fixed.

|
Yesterday night we tested T1, T2, T3, T4, T5, and T6.
All telescopes (except T6 which still have a "tripping" CsI) have an Energy and Time signal on X and Y!

Ongoing, e744, Sat Apr 28 13:27:26 2018, Valerian and Iulian, MUST2, Hardware, 3-alpha, multiples runs with two alpha source on T1 T2 T3 T4 and T5

For the following runs we will use two 3 alpha sources :
On T1, T2, T3, and T4 : [B]11615[/B] : Flux = 1496 alpha in 2 pi

There is an issue with the GMT slave. When you click Online and then apply write hardware, if the message : [U]register error on GMTSlave[/U] appear, [B]reload
a functioning DAS config[/B] and [B]do not write hardware twice[/B].

problem with the cooling system of the M2C chamber, the liquid was in the pipe but it was stopped, no flow, with a lot of "dusts" (vert de gris) => decision |

After increasing the voltage on T5 DSSD from 80V to 100V the resolution increased from ~40keV sigma to 20keV sigma.

After waiting for 1-2 hours. I started the BT again on T5 no tripping BT anymore. While writing hardware with DAS T5 responded well.
After starting the HT, i started a new run :

Today, both cooling system are working fine and their levels are OK.
The vacuum are 7e-6 mbar in M2C and 2e-5 in the 0 degree chamber.
