Abstract: A powdery/granular material flowability evaluation apparatus and a powdery/granular material flowability evaluation method are provided to evaluate the flowability of a powdery/granular material in a dynamic state of the powdery/granular material. The powdery/granular material flowability evaluation apparatus (A) has a hopper (111) for storing a powdery/granular material to be measured, a vertical tube (11) having a flow-in port (1121) connected with a discharge port (1112) of the hopper (111) through which the powdery/granular material is discharged, a vibrator (2) for giving vibration to the tube (11), a laser vibrometer (3) for measuring the amplitude of the tube (11), an electric balance (4) for measuring the weight of the powdery/granular material fallen through the tube 11 from the hopper (111), and an evaluation value calculating section (512) for calculating an evaluation value evaluating the flowability of the powdery/granular material based on the measured amplitude and weight.

Abstract: A sampler introduces charged particles to be measured into an measuring apparatus for measuring charge distribution of the charged particles. The measuring apparatus has a main body, a guide member, and an electric field curtain generating section. The main body has a first opening at upper side and a second opening at lower side, the first opening being adapted to receive the charged particles, the second opening being adapted to discharge the charged particles. The guide member defines a path of the charged particles, the path extending vertically from the first opening to the second opening. The electric field curtain generating section generates an electric field curtain adjacent to a guide surface of the guide member.
