    By cooling the crystal to cryogenic temperature, we could increase θL by another 10% or so [25]. Cooling also helps the crystal transmission efficiency [26]. These options are discussed and evaluated elsewhere [20–24].

    Indeed, the original idea of deflecting ions by a bent crystal was proposed in 1976 by Tsyganov [4], but was experimentally verified only 3 years later by a US-Soviet team at Dubna with 8.4 GeV protons [5]. The new properties of bent crystals were then studied on other accelerators, as the CERN in 1980 [6], Leningrad in 1982 [7], and the FNAL in 1984 [8]. In particular, it has been studied for lots of accelerators applications [9], for beam deviation either directly using channeling [10,11] or volume reflection [12,13], where particles are deviated at typically 1.5 times the critical channeling angle during one glancing collision along a plane.
