SwissFEL 250 MeV Injektor
This linear electron accelerator generates ultra short X-ray beams as a pre-study of the SwissFEL Project.
This cyclotron is dedicated to the high requirements throughout the year for treating patients with tumors by applying protons directly to the lower lying affected cells saving most of the surrounding healthy tissue. This cyclotron also delivers trotons for the treatment of eye tumors. Proton therapy with the COMET cyclotron runs at PSI since 2007.
The Swiss Synchrotron Light Source, SLS, produces synchrotron light e.g. for experiments on protein. This special light is created by sending electrons going almost at the speed of light through strong bending magnets. The light spectrum output ranges from infrared to hard X-ray radiation.

The Cockcroft-Walton and the Acceleration Tube form the pre-accelerator of the Injector-2. The Dome is raised to the electrical potential of 810.000 Volts. The protons are produced from Hydrogen in a microwave powered ion source and first accelerated at 60.000 Volts. The Acceleration Tube adds the above potential to the beam, rising the energy to 870.000 electron Volts. The walls of this housing are electrically grounded to 0 Volts.
Injektor 2
The Injector 2 is a 72 MeV Cyclotron, the pre-accelerator of the Ring cyclotron and can by itself serve the Isotope Production II.
Beam Transporting lines IW2
Several beam lines make it possible to study the beam in order to optimise the parameters (aiming to the beam dump), sending the nominal proton current to the main accelerator (Ring Cyclotron) and / or splitting the beam with electro static elements and magnets to the Isotope Production IP2.

Meson Factory
In the Experimental Hall two rotating cones made out of graphite, Target M and Target E, produce mesons and pions (M being thinner than Target E (mince (fr)=thin, E for épaisse (fr)=thick). The experiments obtain these particles indirectly by collisions between the protons and carbon atoms.
Ring Cyclotron
This cyclotron accelerates the beam coming from the Injector-2 further to an energy of 590 MeV (almost 80% the speed of light) and sends it off in the direction of myon-, pion- and neutron production facilities (both SINQ as UCN produce neutrons from the protons). The idea of building a magnetic field out of separated sectors came from Dr. Hans Willax.
Philips Cyclotron Injector 1
The Injektor-1 was from 1969 until 1984 the pre-accelerator of the Ring cyclotron. After 1984 the Injektor-1 produced protons for the eye proton-therapy treatment facility OPTIS and served experiments with hardrons and heavy ions.

Listing of the facilities & Mile Stones in chronological order

The number of accelerators maintained by this department is growing continuously. Every accelerator is one of its kind and serves a great variety of studies.

In the days of the Swiss Institute for Nuclear research (SIN), new plans were made for a high energy proton acceleration complex. This complex consisted of a purchased cyclotron from the company Philips (Injector-1), a self developed cyclotron (Ring cyclotron) and the connected Meson Factory.

In the year 1984 the new Injector-2 substituted the Philips cyclotron as the main source for high energy proton production. The Injector-1 still provided beam for the low energy experimental areas and the OPTIS eye cancer treatment. At first the Injector-1 served as backup and also provided particle beams for special and rare experiments. After a remarkable 41 years of Service the Injector 1 was decommissioned on the 3rd of December 2010.

In the year 1990 the building of the Spallation source SINQ was started, which made it possible to produce neutrons from the remains of the beam after the Meson factory and it allowed to raise the beam current considerably, which in turn also resulted in a higher gain in the Mesonen Factory. Since 1996 the SINQ is the strongest source of its kind and delivers a continuous flow of neutrons to various experiments.

In June 2001 Swiss Synchrotron light source SLS went online. Although the SLS has exquisit emmitance and brillance from its start, it broke its own record in 2007. In 2011 a world record was reached.

In the year 2007 the first patient was treated at PROSCAN with a beam coming from the super conducting cyclotron COMET.

In the year 2010 the Test-Injector for SwissFEL went into operation. Since the autumn of 2012 the swiss parliament has agreed to build the Free Electron Laser *SwissFEL". Here we have set ourselves the ambitiously high goal to finish in 2016 and produce beam for research.
