unpacker: lmd > root |
|
|
I have written an unpacker for the lmd data taken with the current daq-system for E121.
The crate configuration is as follows:
ADC1 channels 1-32 (Caen 785)
ADC2 channels 1-32 (Caen 785)
ADC3 channels 1-32 (Caen 785)
SCALER channels 1-32 (Caen 830)
The unpacker binary can be found here
/u/litv-exp/unpacker/unpackexps/E121/E121
The current spec file is attached.
To convert lmd-files to root-files, please use it as follows:litv-exp@lxg___: E121_unpacker /path/to/file.lmd --ntuple=RAW,/path/to/new_file.root |
