Liquid Hydrogen Bubble Chamber for Low Energy Nuclear Physics
Journal Article
·
· Review of Scientific Instruments
The bubble chamber contains 3.2 liters of liquid hydrogen and has two vertical and two horizontal windows 4 in. in diameter, which are used for 90 deg stereophotography. The energy and scattering angle of recoil protons from 5 to 38 Mev can be measured. As a neutron spectrometer, the chamber has an efficiency of 8 x 10/sup -3/ recoil protons in the zero-to-30 deg forward cone per incident neutron, at 22.5 Mev. The peak of the energy distribution has a full width at half maximum of 1.3 Mev, and the background is about 4%. The average scanning rate is 2000 tracks per man-week. A description of the apparatus and track- measuring equipment is given. (auth)
