How to use the polarization from the beam properties class in MCWrapper?

[aaust]

I am trying to simulate events with a realistic polarization measured by TPol. The beam properties class provides the possibility to set the ROOTTPolFile, but I don't know how to do it through MCWrapper.

I use the key words TEMPBEAMCONFIG and TEMPPOLANGLE in my gen_amp configuration file, but the beam configuration file is generated locally at run time and does not have the polarization in it. The events are therefore generated with a fixed polarization = 0.4.

Hi Alex,

as far as I am aware this is currently not possible using the webform. But you can do this via your MC.config file if you run MCWrapper yourself. For an example please have a look at

gluex_MCwrapper/examples/MC.config

Line 28 in 9ed8a41

#POL_TO_GEN=/[full path]/tpol.root:pol_hist

@T-Britton If is see this correctly you have the backend in place (with a minor bug) here:

gluex_MCwrapper/gluex_MC.py

Line 397 in af5ae22

COMMAND_parts['polarization_to_generate']="../"+flux_to_use #"/srv/"+tpol_to_use

So we would only need to add a column in the db and a field on the submit form to get this to work?
