Focusing by symmetrical triplets is studied for the linear accelerator lattices in recirculating muon accelerators with several passes where the ratio of final to initial muon energy is about four. Triplet and FODO lattices are compared. At similar acceptance, triplet lattices have straight sections for the RF cavities that are about twice as long as in FODO lattices. For the same energy gain, ...

State-of-the-art techniques derived from particle accelerators, detectors, and physics computing are routinely used in clinical practice and medical research centers: from imaging technologies to dedicated accelerators for cancer therapy and nuclear medicine, simulations, and data analytics. Principles of particle physics themselves are the foundation of a cutting edge radiotherapy technique fo...

testicular germ-cell tumors are the most common malignancy among men aged 20-40 years, and 60 percent of them are seminomas. these tumors are now an important socio-economic problem, considering their growing incidence. thus we undertook to evaluate the results of curative irradiation in our testicular seminoma patients and compare them to literature results considering the use of cobalt-60 sys...
