Primary Project Goal

The primary project goal is to provide 4 pass acceleration of 1 mA beam to 150 MeV, then decelerate in 4 passes and dump.

The energies are defined as follows:

    • Instructions:
      • get the present values of the quad's gradients 'caget MER2QUA01 _field' by going to the epics control system: ssh -X erpopr@erp201
      • 1. run tao
      • call VaryQuads.tao
      • call Commands2.tao
      • run (runs 100 steps
      • In the case that you want to change the number of quads to vary you have to edit the Commend2.tao where you can ask:
        • use var q.r2[4:8] (this line can pick the quads you want: for example use var q.r2[6:8] will var RXQUA03, RXQUA02, and RXQUA01 at the end of the RX line.
          use dat twiss.la_will[7:12] This line says that from 7--> 12 in the twiss.la_will the contraints for aplha_x, aplha_y, beta_x, beta_y, dipersion at the end of the MR1DIP01 /3 (4, 5) and the dipersion prime to be all zero
