=== how to merge background in sim ============

here is an example what Zhiwen think how to merge signal and background in sim
// 1.assume beam current 15ua and 50ns time window. we have 15e-6/1.6e-19*50e-9=4.7e6 beam e- within 50ns time window
// 2.assume the background "beamontarget" sim file is from 1e10 e- with 10x actual target density and it has 1e5 number of events with hits in at least one detector.
// 3.beamontarget file has 1e10/4.7e6 = 2128 number of time window.
// 4. for each signal particle in sim, we should add 1e5/10/2127=5 background event from beamontarget file randomly for every detector channel, then output in csv
// 5.for GEM, we need to use 300ns time window. all other detector use 50ns. so GEM needs to add 6 time more background events for each signal event
