A very compact solar neutron detector is made by using scintillation fiber and multi-anode photomultipliers. Signals from the 512 channels of the photomultipliers are read-out by CMOS circuitry which has been developed for a KEK B-factory experiment.

We present here a search for possible short-term (~seconds to hundreds of seconds) variability of emissivity of the Crab pulsar (beyond the 33 ms pulsation) in gamma rays at E > 50 MeV and on possible correlations between giant radio pulses and high-

Recent observations of the Crab pulsar by the Energetic Gamma-Ray Experiment Telescope (EGRET) on the Compton Gamma Ray Observatory show that the high-energy gamma-ray light curve has changed little over the lifetime of the instrument. Previous data

The gamma-ray pulsar PSR B1509-58 and its surrounding nebulae have been observed with the CANGAROO 3.8m imaging atmospheric Cherenkov telescope. The observations were performed from 1996 to 1998 in Woomera, South Australia, under different instrument

We detected a sixth high-energy gamma-ray pulsar, PSR B1951+32, pulsating in gamma rays at E ≥ 100 MeV with the same 39.5 ms periodicity as in radio, using the data obtained during 1991 May to 1994 July by the Energetic Gamma Ray Experiment Telesco
