Peak Hop DefinitionΒΆ
This section describes how to define a peak hopping sequence.
A peak hop sequence, HOPS
, is a list of peak hops (i.e magnet moves).
HOPS=[('Ar40:H1:10, Ar39:AX, Ar36:CDD', 5, 1),
('Ar37:CDD', 5, 1)]
A peak hop
is a list of iso:detector
pairs plus two configuration values,
the number of counts at the current position
the settling time (s) after magnet positioning and before measurement starts.
The first iso:detector
pair of each hop is used for positioning.
To specify a non-nominal deflection value for a detector use iso:detector:deflection
Ar40:H1:30
If no value is specified and the deflection value had been changed by a previous cycle then the deflection is set to the value stored in the spectrometer configuration file.
The following sequence,
('Ar40:H1, Ar39:AX, Ar36:CDD', 10, 1)
('Ar40:L2, Ar39:CDD', 20, 5)
translates to
position Ar40 on detector H1, wait 1s and record 10 H1,AX,and CDD measurements.
After 10 measurements position Ar40 on detector L2, wait 5s, then record 20 measurements.
