Silicon Raw Data, Hits, Clustering, and dE/dx

Raw Data


• Description of the Raw Data Format: web page , D0 Note 3829 (R. Illingworth)



• Code:
• unpack_svx_fe - unpacking SMT raw data
• smtraw - creates the SMT data chunk from the unpacked data (and vice-versa)
• smtdata - SMT data structure
• smtutil - strip address utilities and address translation code


• Inputs:
• A configuration file, cfg.dat, associated with run_config_mgr - the run configuration manager
• An address translation map, derived via Python script (in smtutil) from the SMT hardware database.


• Additional documentation:
• The SMT hardware database (F. Blekman)
• The initial SMT address translation spreadsheet (B. Quinn)


• Accessories:
• svxrawdump - tool for displaying the raw data from SVX based detectors (instructions)


• Archive:
• Old smtraw documentation (J. Rha), find here a description of the dynamic calibration procedure.
• Map of SVXII readout electronics to SMT detector elements (M. Narain), this ideal mapping is currently only used in MC.

Hits and Clusters



• Description of the Clusters/Hits class diagrams (D. Norman)



• Code:
• smt_input - interface to the SMT data structure
• smt_cluster - cluster (1D)
• smt_lpos - position of clusters
• smt_hit - hit (2D)
• smt_hitalgs - algorithms
• smt_hitpackages - reconstructors
• Running the code


• Archive:


• D. Norman's old web pages on the hit classes
