[Tpe] trigger

[Puneet Khetarpal]

Hi All,

Here is the trigger setup that has been decided for TPE for now.
Please take a look and suggest any changes / modifications. Sergey and
Co. would like us to give them a final trigger configuration for the
experiment as we are asking for special triggers and they would like
to make sure the trigger is configured appropriately to meet our
needs:

Primary Trigger (critical, can't do experiment without it):
========================================
TOF Sec 1 Panel 1 x EC Sec 1 AND TOF Sec 4 Any panel
TOF Sec 2 Panel 1 x EC Sec 2 AND TOF Sec 5 Any panel
TOF Sec 3 Panel 1 x EC Sec 3 AND TOF Sec 6 Any panel
TOF Sec 4 Panel 1 x EC Sec 4 AND TOF Sec 1 Any panel
TOF Sec 5 Panel 1 x EC Sec 5 AND TOF Sec 2 Any panel
TOF Sec 6 Panel 1 x EC Sec 6 AND TOF Sec 3 Any panel

In the above, "Panel 1" refers to TOF hits within 8 < theta < 45 deg
which is scintillators #1 to #23; "EC" refers to low threshold EC
signal for Minimum ionizing; "Any panel" refers to signal coming from
any part of the TOF sector.

Secondary Trigger (want, can do without it):
================================
TOF Sec 1 Panel 2 x EC Sec 1 AND TOF Sec 4 Any panel
TOF Sec 2 Panel 2 x EC Sec 2 AND TOF Sec 5 Any panel
TOF Sec 3 Panel 2 x EC Sec 3 AND TOF Sec 6 Any panel
TOF Sec 4 Panel 2 x EC Sec 4 AND TOF Sec 1 Any panel
TOF Sec 5 Panel 2 x EC Sec 5 AND TOF Sec 2 Any panel
TOF Sec 6 Panel 2 x EC Sec 6 AND TOF Sec 3 Any panel

In the above, "Panel 2" refers to TOF hits within 45 < theta < 62 deg
which is scintillators #24 to #30.

Level 2 Trigger (desire, can do without it):
==============================
DC Sec 1 Forward x TOF Sec 1 Panel 1
DC Sec 2 Forward x TOF Sec 2 Panel 1
DC Sec 3 Forward x TOF Sec 3 Panel 1
DC Sec 4 Forward x TOF Sec 4 Panel 1
DC Sec 5 Forward x TOF Sec 5 Panel 1
DC Sec 6 Forward x TOF Sec 6 Panel 1

In the above, "Forward" refers to the 0 < theta < 45 degrees in DC. I
am not certain if we can have that in the trigger.

Please let me know if this trigger setup is what we need/want. Please
suggest any modifications or comments as needed. If everything looks
okay then I can give Sergey the final go ahead for this trigger
config.

Thank you,
Puneet
