NMR
From Hchkswiki
Three NMR probes will be used to measure the magnetic field of SPL, HKS dipole and HES dipole. These probes are connected to multiprexer (Metrolab 2032) channel A, B and C, respectively, then singals are transfered to a NMR controller (Metrolab PT2025). A communication module (Metrolab RG2040), which has a RS232c and IEEE-488 interfaces, is inserted on the backplane of the controller. NMR data are sent to PC104 by the RS232c communication.
- RS232c communication configuration is as follows;
Baud Rate : 9600bps Parity : none Data bits : 8 data bits Stop bit : 1bit
- EPICS CA list;
{mag}_nmr_field : magnetic field (Tesla)
{mag}_nmr_status : status (1:locked, 2: unlocked, 3:signal, 4:wrong)
where, {mag} is kd, ed or spl.
