STAR HardProbes PWG

[Carl Gagliardi <c-gagliardi AT tamu.edu>]

Hi Rongrong, All—

 

A note from the peanut gallery…

 

During 2015, the BHT3 trigger bit was utilized for some other purpose.  (I think UPC J/psi, but won’t swear to that.)  Therefore, L2Gamma was fed by a funny composite trigger that included BHT and BJP constraints.  There is a reasonable chance that the BHT3 trigger bit will be freed up.  If so, it would be a natural choice to feed the L2Gamma routine.

 

Stay Healthy!

Carl

Hello Nihar, All I looked through the trigger thresholds and rates from 2015, which could give us some guidance for Run24. -BHT2 -- Threshold: 18 -- Other condition: BBCMB -- Rate: 80 - 180 Hz (end of fill to beginning of fill) -- Prescale:

Hello Nihar, All

I looked through the trigger thresholds and rates from 2015, which could give us some guidance for Run24. 

-BHT2

-- Threshold: 18

-- Other condition: BBCMB

-- Rate: 80 - 180 Hz (end of fill to beginning of fill)

-- Prescale: 1

-- Monitor trigger: BBCMB

-BHT1

-- Threshold: 11

-- Other condition: VPDMB-30

-- Rate: 200 - 600 Hz

-- Prescale: 1

-- Monitor trigger: VPDMB-30

-dimuon

-- Threshold: very loose

-- Other condition: none

-- Rate: 100 - 300 Hz

-- Prescale: 1

-- Monitor trigger: VPDMB-novtx

If the band width is limited, we can probably run BHT1 with a prescale of 2 or 3. 

Best
