[en] The purpose of the Gate-keeper is the control of the RDCs, the ADCs, and the constant fraction discriminator. The Gate-keeper synchronizes the units and ensures that the data taking is clean and not intermixed with other events. There are six Gate-Keepers in the system, one for each proton detector. All input circuits are designed to accept TTL as well as negative NIM signals. The output is 50 ohm TTL or negative NIM as defined by internal jumpers

[en] The FAN-out module is a driver module for three time-to-digital units and one multiscaler unit. The 16 input signals come from the Ortec CO 1600 coincidence unit. Diagrams of the circuits and a component list for the module are given here

[en] The TANSY-KM5 neutron spectrometer is a system containing a lot of advanced electronic and mechanical components. The design of the system has been reported in two documents (CTH-RF--54 (INIS 17:10206) and CTH-RF--43 (INIS 14:797424)). The purpose of this documentation is to give a brief overview of the system as it is defined at the time of delivery

[en] Our first task was to purchase a computer and to create a basic software library for the preliminary test of the components. Our choice was a Starburst system from CES. The computer was a PDP-11/70 on a chip. It is the same computer as the ones used by the auxiliary CAMAC crate controllers in the TANSY system. However, the host has a 256 kbyte memory instead of the 64 kbyte memory used in the crate controllers. The operation system is RSX11-M. It is a real time system with properties suitable for laboratory works. However, the computer works in 64 kbyte partitions which limits the size of the programs. Four program systems were written. The two first were one-parameter systems for amplitude and time measurements using the ADCs and TDCs which later should be included in the TANSY system. These systems were supplemented with two two-parameter systems, one for time and amplitude measurements and one for time measurements on 16 detectors simultaneously. The display capabilities of these program systems have been used extensively by the TANSY programs. The programs needed for the manipulation of the system give the user a possibility to manually run the system without any intervention from the normal CODAS control system. The programs have been used for calibration measurements as well as test of the TANSY system. The evaluation programs use the output file from a normal measurement. The data file may be tested for errors. The true events can be sorted into different configurations. The final one is the neutron energy sort program, which gives the neutron energy distribution

[en] This document describes procedures for the set-up and use of TANSY. It is a complement to the report 'Technical description of the Tansy Spectrometer, TANSY-KM5' (CTH-RF--81) and is aimed to guide the user through the initial adjustments and calibrations to a normal use of the instrument. Details, such as placing of jumpers and settings of potentiometers in electronic modules, are not given here. The calibration parameters obtained during the test period are listed at the end of each calibration chapter. They can be used as a first estimate of unknown parameters
