The detector plane page is used to change parameters of a detector plane and to perform runs on a single plane.
The first step is to select a detector plane. Chose the link number in the combo box select: The name of the detector plane name will appear next to the combo box, if no error occurred (e.g.: no detector plane added to the link).
Description: Readout performs a do_calibrate command, using fifo 0. The occupancy for every channel is measured and written to a file.
Input: The number of events and the file name the data are written to is required.
CB_cal: cal_0.cb 0 CB_cal: cal_2.cb 3two charge injection scans are performed. The first one is using cal_0.cb (analyzing calibration line 0) the second one is using cal_2.cb (analyzing cal-line 3). Input: and Output: are identical (except header word) to those for a charge injection scan.
Description: For a noise scan the occupancy is measured for different threshold values. Triggers are issued by executing the fifo 0. The control block file is not loaded automatically but usually loaded when the system is started.
Input: The inputs are the start, stop and step size for the threshold voltage, the output file name and the number of events. There are two entries for the number of events. max number of events: is the maximum number of events (triggers) that are collected for a threshold point. events is the mean number of hits per channel after a scan point is stopped. Every thousands event the mean number of hits per channel is calculated. If this number is bigger than events the scan point is stopped and the scan continues with the next point.
Only channels that are selected are decoded and used in the analysis. When a detector plane is initiliezed all channels are selected.
