(*) The program for the estimation of target-thickness is mainly for ML(Material & Life)-users.

1. Estimation of target thickness (RIPS-standard) for highest beam-intensity :
   
   This program estimates thickness of the RIPS-standard Be target and the rotational graphite target, which will provide the highest intensity of secondary beam. A heat generation at the Be target will be estimated.


• 1) This program may not be suitable when you will use original targets or you should contrive something to produce a secondary beam.
• 2) If you will use a high-intensity primary-beam which would melt the target, please use the rotational-target system (please contact the person in charge of RIPS in this case).



Input the following parameters:

Primary beam mass number (A):
Primary beam Z (Z):
Secondary beam mass number (A):
Secondary beam Z (Z):
Primary beam energy [A MeV]:
Primary beam intensity [pnA]:






2. Determination of primary-beam's stopping position
   
   Stopping position at RIPS for primary beam should be one of following three places:
   
   (a) Beam dump inside D1
   (b) Slit located at exit of D1 magnet
   (c) F1 slit (stopper)
   

   (A 4-dimension slit at F0 will be also used when you use a beam swinger.) This program calculates a difference of B&rho between primary and secondary beam after passing through the production target, and determines the stopping position among (a), (b) and (c). A heat generation and a cooling power at the beam dump are estimated in the case of (a).




• 1) This program calculates the primary and secondary beam's B&rho for most probable charge states after the target. Please convert to proper B&rho when you will select other charge states.
• 2) The probable charge state is calculated based on a model, so they might not be proper for further detailed investigation.


Input the following parameters:

Primary beam mass number (A):
Primary beam Z (Z):
Secondary beam mass number (A):
Secondary beam Z (Z):
Primary beam energy [A MeV]:
Primary beam intensity [pnA]:
Target material mass number (A):
Target material Z (Z):
Target thickness [mg/cm^2]:
