how about "ACCELERATOR HEALTH PHYSICS" by Patterson circa 1973?

Hi All,
     
     
Of interest to me here is a researcher who is developing a laser based 
accelerator. They predict that their next unit may be capable of producing 
essentially monoenergetic 100 MeV electrons in 50-100 fs pulses repeated 
with up to a 1 hz frequency.  I would appreciate any advice you could 
provide about monitoring equipment  Clearly energy dependance, saturation, 
recombination and calibration are big issues.  Fortunately, the lab is 
reasonably well funded.
     
Certainly shielding is also a big issue.  The beam produced will probably 
be produced with an initial narrow cone (5 cm spread a 50 cm distance). 
Any advice for materials, amounts, shielding codes or references would be 
appreciated.
     
Please send the replies directly to Radsafe.
     
Thanks!
