Laboratory of the VdG accelerator

Institute of Experimental and Applied Physics, Czech Technical University in Prague

The laboratory of the Van de Graaff accelerator is devoted to basic and applied research in experimental nuclear physics. Applications include testing and calibration of radiation detectors and the development of analytical methods in related areas (material and surface analysis, high-energy physics, space-related research). The laboratory is part of the Institute of Experimental and Applied Physics (UTEF) of the Czech Technical University (CTU) in Prague. Besides serving as a source of light ions the facility serves namely as tunable source of mono-energetic neutrons in relatively wide energy range (100 keV - 19 MeV). Experiments are mainly performed with charged particles (p,d,4He) and fast neutrons (from D-T, D-D and p-T reactions). In addition to the accelerator, the laboratory houses two stations of discrete gamma rays (described below). Access to the accelerator, beam guides and experimental chambers as well as the ESA gamma-ray stations (links included below) is possible all year round (see contacts).

Light ion beams & tunable mono-energetic neutron sources

Continuous beams are provided as follows. Light ions can be also provided in low intensity (down to 10^3/cm^2/s). Neutrons of discrete energy (accuracy few %) are provided in the indicated ranges. The neutron sources are calibrated and monitored with active devices (liquid scintillator NE 213, 3He Bonner sphere) with online display and evaluation.

light ions				monoenergetic neutrons
protons	E = 0.2 - 2.2 MeV	I = 0.5 - 10 uA		D-T:	E = 14.1 - 18.9 MeV	Φ = 103-5 n/cm2/s
deuterons	E = 0.2 - 2.2 MeV	I = 0.5 - 10 uA		D-D:	E = 2.5 - 5.7 MeV	Φ = 102-4 n/cm2/s
4He	E = 300 keV/u - 2.2 MeV/u	I = ~ uA		p-T:	E = 0.03 - 1.7 MeV	Φ = 103-5 n/cm2/s
12C,14N (newly)	E = 300 keV/u - 2.2 MeV/u	I = ~ uA

Accelerator beam guides

The accelerator is equipped with 5 operating beam guides on which experimental setups are mounted. Guides 0,P1,P2,P3 deliver charged particle beams, guides L2,L3 provide the neutron sources.

Experiments/techniques, vacuum chambers, installed detectors/monitors, DAQ readout electronics

Experimental setups are mounted on the 5 installed beam guides for a number of techniques (listed). Vacuum level is 10^-5 mbar. Most lines are equipped with turbo-molecular vacuum pumps. The laboratory is equipped with a range of coaxial cable lines for transmission of measured signals from the accelerator hall to the control room and specially to the DAQ and evaluation room including several Ethernet lines for intranet within (after registration with the network administrator) as well as for remote transmission of data over the Internet. The laboratory is also able to ensure, if necessary, supply of liquid nitrogen and liquid helium. We also provide dosimetric monitoring service with our own experiments dosimeters.
