- The MEGA experiment, which is a search for the decay murarregamma with a branching ratio sensitivity of about 10-13, employs highly modular, fast detectors, state-of-the-art electronics, and a staged trigger with on-line filters. The detectors are contained in a 1.5-T solenoidal field produced by a superconducting magnet. Positrons are confined to the central region and are measured by a set of thin MWPCs. Photons are measured by one of four layers of pair spectrometers in the outer region. Most aspects of the design have been validated in engineering runs; data taking will begin in 1990 with much of the electron arm and one pair spectrometer layer installed.

Journal article (peer-reviewed)abstract
- We have previously observed that elevation of the plasma glycine concentration stimulates vasopressin (AVP) release in man and sheep. In the present study we show that this effect of glycine can be elicited directly via a cerebral site of action in conscious sheep. Intracerebroventricular infusions of 0.05 and 0.15 M glycine solutions increased the plasma AVP concentration by 6 and 50 times, respectively, while no effect on water intake was observed. Hyperhydration did not block the stimulation of AVP release. No behavioural side effects, or changes in blood pressure, were observed in response to the infusions.
