# TAS Data Storage

Triple axis spectrometer data is stored in ASCII files. These ASCII files are formatted in a format compatible to the ILL's triple axis data file format. Data files can be found in directories:

        /home/INST/data/YYYY/HHH

on the instrument computer or in

        /afs/psi.ch/project/sinqdata/YYYY/INST/HHH

on any other LNS unix system. INST is a placeholder for the instrument name in capitals, YYYY for the year of data collection. HHH is the thousands directoy. In order to facilitate file handling, data files are grouped into directories containing thousand data files each. Thus files 0-999 will be in the 000 directory, files 1000-1999 in the 001 directory etc. Data files are named according to the SINQ naming convention:

         instYYYYnTRRRRR.dat

with inst being the placeholder for the instrument name in lowercase, RRRRRR the run number as a six digit number and YYYY again the year of data collection. Example: tasp2002n000330.dat is data collected in run number 330 in 2002.

The last measured data file can be discarded by typing the command:

    killfile

in SICS. SICS managers privilege is required for this command.

Automatically generated log files can be found in the /home/INST/log directory for each day. They are named according to the scheme:

    autoYYYY-MM-DD@HH-MM-SS.log

YYYY is again the year, MM the month, DD the day, HH the hour, MM the minute and SS the second of file creation.
