Hi,

I will start working on this today afternoon;
we should have something ready by Monday.

Cheers,

 Hello Alexander ,

We have decided on the CPP meeting, that we will need to have only the inner layer modules of FCAL excluded from the trigger, and no others. Same time we want to remove TOF-3-bits prescaled trigger to compensate for this modification in the rate.
If it is not possible for you to do it today, it needs to be done on Monday.

 All the best.
 Ilya

Hi,

Some quick tests we can do soon, when the beam is back, tomorrow or on Friday
(fine-tuning and checking may require some time though).

The overall rate is relatively high, if we push it up there could be some DAQ instabilities;
we already have some minor issues now (likely due to the FDC readout).

Cheers,
              Sasha

 Hello Sasha,

on today's CPP/NPP meeting we have decided to check if we are able to take our data at the reasonable rate without masking FCAL channels if any, specifically we want to include inner calorimeter layers in the trigger.
If the rate will be too high, we will need to exclude only the most inner layer from the trigger. Also we want to double-check if there are no other channels masked from the triggering. Please, schedule this update to your earliest convenience, and let us know.
 Thank you,
 Ilya
