The use of proton transmission energy loss ( ptel ) method to measure mass density of aerosol on mylar film 质子透射能量损失(PTEL)测量气溶胶样品面密度
Similar to PANI membrane, the swelling ratio decreased a lot and proton conductivity decreased a little, but the weight loss ratio declined dramatically. 复合膜溶胀度显著降低,质子传导率略有下降,但质量流失率显著降低。
High-current proton linac sets a very severe requirement on the control of beam loss and emittance growth. 强流质子直线加速器要求严格控制束流损失和束流发射度增长。
