Abstract

A new beam analysis system has been installed at the Berkeley 88″ cyclotron. The system consists of two 110° flat field, edge focusing bending magnets. The first magnet is used to energy analyze the cyclotron beam, and the second or “clean up” magnet is used to remove slit scattered particles produced by the analyzing magnet. The system has achieved its design performance of 0.02% energy resolution, with a long term stability of two parts in 10⁵. Up to 0.6 μA of a beam with a radial emittance of 4.5 mm·mrad has been obtained with the above energy resolution.

This paper describes the design, construction, installation shimming and testing of the magnets, as well as the construction of the regulated power supply.

The design and calibration of a high efficiency deuteron tensor polarimeter
1980, Nuclear Instruments and Methods
We report on the detailed design and calibration of a novel, high-efficiency polarimeter for tensor polarized deuterons. This device measures the t₂₀ moment of the deutron, and was built to observe the polarization of recoil deutrons from 180° π−d elastic scattering. Based on the ³He(d, p)⁴He reaction at low energies and forward angles, the polarimeter detects 1.8×10⁻⁴ protons/incident deuteron with an average analyzing power of T₂₀ = −0.6.. The performance of the polarimeter in high background fluxes is discussed.
A new method for calibrating the pulse-height defect in solid state detectors
1978, Nuclear Instruments and Methods
The pulse-height defect (PHD) of a Si surface barrier detector (1000 ωcm resistivity) has been measured with a cyclotron for elements from Kr to Au between energies of 15 to 160 MeV, and for elements from Ne to Fe between 5 and 50 MeV. A simple power-law formula for relating the PHD to the total energy is described. A procedure for calibrating a Si detector for the PhD from measurements for several elements has been developed and tested. This procedure reproduces the data to within the experimental error (±0.5% of the total energy). Application of the measured and calculated PHD values to another detector of similar resistivity seems to be accurate to better than 10% of the PHD. Our PHD data are also compared to an existing PHD formalism.

Energy stabilization of an isochronous cyclotron beam with an external monochromator control
1976, Nuclear Instruments and Methods
A very high energy stability of an isochronous cyclotron beam can be achieved with a feedback control of the Dee-voltage where the feedback signal is taken from the analyzing slit of a monochromator system. The principle of regulating is described with the aid of the energy-phase distribution of the beam pulses. The residual instabilities of the rf-amplitude and/or the rf-frequency are well compensated. A fast response can be achieved. The practical realization of a feedback controlled energy stabilization at the Bonn Isochronous Cyclotron yields a short- and long-term stability of better than 1 × 10⁻⁴. The developed feedback control can be applied to other isochronous cyclotrons, too, especially to the large separated-sector machines.
Ultra-high resolution measuring of beam momentum distributions
1975, Nuclear Instruments and Methods
A simple and direct measuring method has been developed in order to determine precisely the momentum spread of highly resolved particle beams. An extremely high analyzing power of more than 100 000 can be achieved with simple deflecting magnets by an arrangement of extremely narrow slits. In order to discriminate against slit-scattered particles a semiconductor detector with a good energy resolution is used as beam current meter behind the analyzing slit. A homogeneous scanning of the beam to be analyzed is achieved with steering units. The method can be applied to all kinds of charged particle beams. It has been successfully used to measure the momentum spread of 3.5 × 10⁻⁵ of a 14 MeV proton beam. Further applications and modifications are discussed.
The beam handling system at the bonn isochronous cyclotron
1975, Nuclear Instruments and Methods
The lay-out and the ion-optical structure of the beam handling system at the Bonn Isochronous Cyclotron is described. The following beam preparation modes are possible with two double monochromator systems: (1) double dispersive with an extremely high momentum resolution of 30 000; (2) double dispersive with an adjustable dispersion matching with a magnetic spectrograph; (3) nondispersive, nearly isochronous, variable momentum resolution up to 8000, adjustable time of flight resolution below 0.5 ns; (4) achromatic with a transmission of 100%. The practical experiences in operating the system and achieving the design performances are discussed. The results of rigorous test measurements are given.
