An electronic instrument for indirectly determining the peak kilovoltage of diagnostic x-ray machines
The instrument described has been developed through several stages over a period of three years; the detector is based on a rare earth fluorescent screen and the complete instrument is relatively simple to construct. The performance of this instrument has been evaluated, and comparison with an independent assessment of a number of the commercial instruments (Rothenberg and Fleischman, Med. Phys., vol.9, p.613, 1982) has shown that this instrument has a measured performance compatible with those commercial instruments tested.

Measurement of the decay K{sub L}{sup 0} yields {pi}{sup 0}{pi}{sup 0}
A measurement of the rate {Gamma}(K{sub L}{sup 0} yields 2{pi}{sup 0} has been made relative to three other rates in a spark chamber scintillation counter experiment. Results are given, which show agreement with the previous average.

Use of a monolithic dual JFET in a low cost, low noise, charge-sensitive preamplifier for semiconductor radiation detectors (medical application)
A charge-sensitive preamplifier can be simply constructed utilising a 2N5566 monolithic dual JFET with the two FET connected in parallel. The noise performance for this preamplifier is comparable to that for a commercial low noise preamplifier under normal operating conditions. The circuit is unsophisticated, requiring few components, facilitating ease of construction provided attention is paid to the points mentioned. The cost of the components is less than Pounds 20 and can be contrasted to that for commercial devices of several hundred pounds.
