Hodoscope detectors

Three pieces of Hodoscope detectors for beam position monitoring are available. Two of them are identical with scintillator rod dimensions 100 x 10 x 5 mm, the third one has smaller rods (100 x 6.5 x 6.5 mm). All three detectors show significant light attenuation inside the scintillators and had to be repaired in Optical laboratories of the Charles University in Prague, Czech Republic.

Attenuation before repair

Attenutaion length before repair was 4 - 7 cm depanding on the rod and method of measurement (cosmic muons, gamma or beta radiation).

After repair

Attenuation length after exchange of scintillator rods is cca 24 cm.

QA over web browser:

open web browser from any machine in GSI network: hades33/mon/

or from outside: http://cerberus.x-matter.uni-frankfurt.de:8888/mon

or from WiFi: http://cerberus.x-matter.uni-frankfurt.de:3060/mon

OR via SOCKS proxy setting:

1. open a ssh connection and activate 'dynamic port forwarding'
ssh -D 1080 USERNAME@lxi001.gsi.de

2. Setup SOCKS proxy in Firefox
Edit->Preferences->Advanced
open tab 'Network'
click on Connection 'Settings...'
activate 'Manual Proxy Configuration'
setup:
SOCKS Host: localhost Port: 1080
(ensure that all other Proxy fields are blank (or 0))

How to analyze the data (may 14 test):

QA was moved to hadestof@lxhadeb06.gsi.de

0.) go to folder /analysis/tof/May14

1.) to find last 20 hld files type:

zsh

ls -ltr /store/**/*.hld(.om[0,20]L+33)

2.) run defall.sh placed in the /makeDST/ folder

3.) use analysis macro from /makeDST_ilse to analyse the files (./analysisDST name_of_the_file_from_step_1 number_of_events)
