Cosmic Ray NM-64 Neutron Monitor Data-18

摘要

Pressure corrected data from the Rome (Italy) neutron monitor and barometricpressure data are given in tabular form for the year 1989, together with the graphs of the corrected intensity. The atmospheric pressure was measured by two digital barometers: one based on a high resolution force balance pressure transducer; the other based on a high accuracy capacitance sensor. The five minute rates of the monitor sections are recorded with the barometric value. The stability of the monitor is controlled by means of the section ratios. Periodical checks of the electronic equipment and multichannel tests of the counters are made. The pulse height distributions of the amplifier output pulses together with the discriminator input-output coincidence pulses, allow us to follow the stability of the gas pressure in the counter, high and low voltage power supplies, amplifier, and discriminator.
