DESCRIPTION:Speakers: Sergey S. Kurennoy (Los Alamos National Lab)\n\nIncr
 easing energy of proton beam at the Los Alamos Neutron Science Center (LAN
 SCE) from 800 MeV to 3-5 GeV will improve radiography resolution ten-fold.
  This energy boost can be achieved with a compact cost-effective linac bas
 ed on normal conducting high-gradient (HG) RF accelerating structures oper
 ating at liquid nitrogen temperatures (cryo-cooled). Such an HG booster is
  feasible for proton radiography (pRad)\, which requires short beam pulses
  at very low duty. The pRad booster starts with a short L-band section to 
 capture and compress the 800-MeV proton beam from the existing linac. The 
 main HG linac will be based on S- and C-band cavities. An L-band de-bunche
 r at the booster end can reduce the beam energy spread if needed for pRad 
 experiments. We are developing proton cryo-cooled HG structures with distr
 ibuted RF coupling for the booster. Prototype cavity structures at S- and 
 C-band are designed and will be tested cryo-cooled to measure breakdown ra
 tes at high gradients. The booster linac beam dynamics design and prelimin
 ary proton radiography simulations will also be discussed.  \n\nhttps://i
