Neutron facilities

Neutron Time Of Flight

The Neutron Time Of Flight (n-TOF) facility is a neutron spectrometer at CERN. It consists of a pulsed source, a flight path of 200 m length, and a detector systems. Neutron energies are deduced from the time of flight between source and detector; hence the name of the facility. The neutrons are produced by neutron spallation; by directing a pulsed beam of protons from the Proton Synchrotron (PS) towards a lead target about 300 neutrons expelled for each impact of a proton. The neutrons are slowed after being emitted, first by the lead target and afterwards by a slab containing water. This results in a wide range of neutron energies since some neutrons will slow down more than others when passing through the targets. Finally, the neutrons are ejected through the 200m long flight path before they arrive at an experimental area. (Wikipedia).

Lec 35: Professor Lewin’s Early days at MIT | 8.01 Classical Mechanics, Fall 1999 (Walter Lewin)

Professor Lewin talks about some of the highlights from his early days at MIT. It began with balloon flights at very high altitude to make observations of the stars in X-rays. This led to discoveries of X-ray flaring events and a periodic X-ray source (GX 1+4). In the seventies and eightie
