Introduction

In the frontend, data is read from the VME scaler(s) (SIS3801 or SIS3820) and saved in histograms. The number of histograms is greater than the number of active scaler channels. For example, some scaler data are saved in separate histograms according to the helicity. In the case of Type 1 runs, the histograms are sent every cycle, whereas for Type 2 the histograms are accumulated in the frontend memory, and sent every few minutes. A data logger running on the host computer saves the data onto disk. The data is handled differently for Type 1 and Type 2 runs. For Type 1 runs, the data are saved in a MIDAS file by mlogger, and converted to MUD format by mdarc. For Type 2 runs, mdarc saved the data directly in a MUD file, and no MIDAS file is produced.

The histograms and data logging will therefore be described separately for Type 1 and Type 2 runs.

Front-end histograms and Cycle Scalers

Scaler Channels : Hardware Connections

Currently,

  • experiment bnmr has two SIS3801 scalers
  • experiment bnqr has one SIS3820 scaler
NOTE
The sis3820 scaler is needed for bnqr alpha mode as it has a larger buffer and greater resolution.

BNMR

Table 1 : BNMR Scaler A Channels
Scaler Module Channel Contents
A SIS3801 1 Front scalers (16 segments summed in hardware)
2 Front scalers (16 segments summed in hardware)
Total number of real scaler inputs : 2


Table 2 : BNMR Scaler B Channels
Scaler Module Channel Contents
B SIS3801 1 Scaler Internal Clock (not connected)
2 Fluorescence Monitor (not used)
3,4 Polarimeter counters (2)
5,6,7,8 Neutral Beam Forwards counters (4)
9,10,11,12 Neutral Beam Backwards counters (4)
Total number of real scaler inputs : 12


BNQR

Table 3 : BNQR Scaler B Channels
Scaler Module Channel Contents
B SIS3820 * 1 Scaler Internal Clock (not connected)
17 Fluorescence Monitor (not used)
18,19 Polarimeter counters (2)
20 Neutral Beam Forwards counter (summed in hardware)
21 Neutral Beam Backwards counter (summed in hardware)
22,23,24,25 Alpha Counters
Total number of real scaler inputs : 10
NOTE
* SIS3820 module has ECL inputs 1-16, NIM 17-32. Therefore BNQR's input channel start at 17 (NIM).
