Finding items on the beamline / lattice
- FACET-II lattice (on facetsrv):
/usr/local/facet/tools/facet2-lattice/Lucretia/models/FACET2e/FACET2e.mat
Script for parsing this file: read.py - Output of the script:
- Get a PV, e.g., from the FACET DAQ file:
- Find z_pos for this PV using findpv:
e.g.: findpv TORO:LI20:1988%

Beamline Lattice via Lucretia
Dipole magnet settings
- Nominal dispersion: 5-6 cm at the dump
Dipole-dump distance: 13.27 m → angle: 4.52 mrad → kick: 45.2 MeV (based on 6 cm for 10 GeV)
Beamline in sector 20
It looks like the documentation of the Quads is wrong
