“…According to momentum calculations, the therapeutic energy (70-218 MeV) of the LMA-SC gantry is divided into three energy bands in Table 1. 19 Switching energy bands takes 10 s, whereas switching energy within one band only takes 16 ms per step (around 5 mm water depth) using current fast servo linear motors. 19,28,29 And the speed of spot switching and line switching is 30.0 and 9.0 mm/ms, respectively.…”

“…But, it increases the transverse beam emittance and momentum spread, which eventually leads to beam loss 29,30 . To minimize these side effects, several groups have optimized the geometry structure and used materials with low atomic numbers and high density 31,32 . Moreover, Maradia et al.…”

“…29,30 To minimize these side effects, several groups have optimized the geometry structure and used materials with low atomic numbers and high density. 31,32 Moreover, Maradia et al developed a beamline that transports a larger emittance beam (100 π⋅mm⋅mrad) using asymmetric collimators. 33 The beamline resulted in the overall transmission increased by 40%, especially for the 70 MeV beam, where the transmission was improved from 0.13% to 0.72%.…”
