Basic Equipment in Hall C
For the Fall 2017 run, see intructions at https://hallcweb.jlab.org/wiki/index.php/How-to
The formulas and program should be kept in sync with the repository.
- Formulas used for setting current of SHMS magnets during KPP
|HB||Current = 330.05*p - 3.1784*p^2 + 0.4018*p^3|
|Q1||Current = 222.4*p - 7.709*p^2 + 0.6684*p^3|
|Q2||Current = 3661*p/11|
|Q3||Current = 2434*p/11|
|Dipole||Current = 3450*p/11|
