在京都大学的一个新的存储环S-LSR上观察到了质子的有序化。在25、50和100 mA的电子冷却下，首次观察到粒子数约为2000的质子的动量扩散和肖特基噪声功率的突变。在纵向和横向的转变温度分别为0.17和1 meV。质子束在跃迁时的横向温度远低于电子的横向温度，这对质子的有序化起着至关重要的作用。
The ordering of protons has been observed at a new storage ring, S-LSR, at Kyoto University. Abrupt jumps in the momentum spread and the Schottky noise power were observed for protons for the first time at a particle number of approximately 2000, upon applying electron cooling with electron currents of 25, 50, and 100 mA. The transition temperature was 0.17 and 1 meV in the longitudinal and transverse directions, respectively. The transverse temperature of the proton beam was much below that of electrons at the transition, which played an essential role in the ordering of protons.
