Book Description
An experimental search for the lepton-family number nonconserving decay, .mu. .-->. e.gamma gamma., has been conducted at the Clinton P. Anderson Meson Physics Facility (LAMPF) using the Crystal Box detector. The detector consists of a modular NaI(Tl) calorimeter, scintillator hodoscope, and a high-resolution, cylindrical drift chamber. It provides a large solid-angle for detecting three-body decays and has good resolutions in the time, position, and energy measurements to eliminate unwanted backgrounds. No evidence for .mu.+ .-->. e+.gamma gamma. is found, giving an upper limit for the branching ratio of GAMMA(.mu. .-->. e.gamma gamma.)/GAMMA(.mu. .-->. e nu anti nu) less than or equal to 7.2 x 10−11 (90% C.L.). This result is an improvement of more than two orders of magnitude in the existing limit. 109 refs., 39 figs.

Book Description
The MEGA experiment is designed to search for the lepton-flavor number non-conserving rare decay [mu] [yields] [ital e][gamma]. Data- taking is complete, with 450 million events on tape taken over approximately 10[sup 7] seconds. A small portion of the data sample has been processed through the complete event reconstruction codes to search for the [mu] [yields] [ital e][gamma] process. No evidence for the [mu] [yields] [ital e][gamma] decay is observed at a sensitivity of [approximately]7 x 10[sup -11] (90% confidence).

Book Description
The status of the MEGA experiment is described. It is a search for the decay [mu] {r arrow} e[gamma] with a branching ratio sensitivity of approximately 10−13. The observation of this decay would indicate the existence of physics outside the standard model of electroweak interactions. The experiment 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 detector design have been validated in engineering runs; data taking will begin in 1990 with most of the electron arm and one pair spectrometer layer installed. 5 refs., 4 figs.
