The Advanced FEL at Los Alamos embodies a K 2 CsSb photocathode as an electron source. The photocathode consists of a K 2 CsSb film deposited on a molybdenum plug that can be inserted into the linac of the FEL. However, because K 2 CsSb is easily con

The Advanced Free Electron Laser (AFEL) is a compact, infrared, rf-linac FEL that uses a high-brightness photoinjector and a short-period permanent-magnet wiggler. Lasing at saturation with and without sidebands has been achieved over the 4--6 {mu}m

The Los Alamos compact Advanced Free Electron Laser (AFEL) has lased at 4.7 and 5.2 μm with a 1-cm period wiggler and a high-brightness electron beam at 16.8 and 15.8 MeV, respectively. The measured electron beam normalized emittance is 1.3 π mm mr

We have designed and are building a subpicosecond electron injector. The injector is based on an 8 MeV photoinjector, used previously at Los Alamos in the APEX experiment. The nominal design includes magnetically compressing a 20 ps long, 3 nC bunch

A precision measurement of the energy dependence of the asymmetry of the decay of the positive muon has been made with a wire spark-chamber spectrometer of large momentum acceptance. We find, as an average of runs at different fields and with differe

The isotope shifts for the muonic X-rays of lead have been found to be about half those predicted for an A 1 3 dependence for the nuclear radius in agreement with optical data. The Kα 1 /Kα 2 and Lβ 1 /Lα 1 intensity ratios are significantly smal

Samples of foraminiferal ooze from two North Atlantic cores were cleaned and progressively dissolved. Most of the P, Fe, and Mn was released during the first of two reductive cleaning steps. Most of the remainder of these elements and most of the Ca
