SoLID Study

Introduction

This is page is collection of study using SoLID software

the code are at https://jlabsvn.jlab.org/svnroot/solid/study/

full simulation and file sharing (Zhiwen)

We will run full simulation with all subsystems and generate various files at a shared central location

They can used for studies like trigger, background, GEM etc and ensure consistent results

list of study

Generator

new electron generator combining both DIS and resonance region with existing code (?)

new hadron generator (Rakitha)

GEM related

GEM digitization validation(?)

Extract information from

1. some cosmic or beam test with charge particles
2. the latest UVa xray test result (p13 of here) 

This is to provide input for digitization, including energy threshold (Solid_GEM_Digitization#GEM_response), cluster width, avalanche charge, efficiency for both charge particle, and efficiency for low energy photons which dominates the background in SoLID, and more.

SoLID GEM digitization is based on the SBS GEM digitization

According to Evaristo, the SBS GEM digitization is "Unfortunately not validated; we used the old COMPASS data to validate the digitization"

Maybe the way to extract some information is do standalone GEM simulations matching test?

neutron background (Lorenzo)

with low neutron physics on, comparing to Fluka result
