Abstract

With the move of the ISOLDE facility to the PS-Booster from the now closed Synchro-Cyclotron at CERN, a new control system will be implemented for the two separators. Personal computers, based on the Intel 80386 microprocessor running under MS-DOS and Microsoft Windows, are used. Network-wide distributed front end computers, which access the hardware for controls and measurements, are controlled by PC-consoles via a local area network with a PC file server used as a database.

Pulse shape of the ISOLDE radioactive ion beams
1997, Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and Atoms
The 2.4 μs proton pulses from the PS Booster are delivered to the ISOLDE targets at a low repetition rate (typically 0.4 Hz). However, the synchronously produced radioisotopes have partially lost this time structure due to the delay incurred by the mass transfer processes used in their conversion into an ion beam. Since the pulse shape of the ion bunches is a vital information for the target development and the experiments, new techniques have been developed to measure it. These methods as well as the mathematics used for calculating the production yield will be described in detail. The limits of the techniques are discussed and a set of examples are presented.
The evolution of the ISOLDE control system
1997, Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and Atoms
The ISOLDE on-line mass separator facility is operating on a Personal Computer based control system since spring 1992. Front End Computers accessing the hardware are controlled from consoles running Microsoft Windows^™ through a Novell NetWare4^™ local area network. The control system is transparently integrated in the CERN wide office network and makes heavy use of the CERN standard office application programs to control and to document the running of the ISOLDE isotope separators. This paper recalls the architecture of the control system, shows its recent developments and gives some examples of its graphical user interface.
Beta-decay to the proton halo state in <sup>17</sup>F
1993, Physics Letters B
In the first experiment at the newly constructed ISOLDE Facility the first-forbidden beta-decay of ¹⁷Ne into the first excited state of ¹⁷F has been measured. It is a factor two faster than the corresponding mirror decay and thus gives one of the largest recorded asymmetries for beta decays feeding bound final states. Shell-model calculations can only reproduce the asymmetry if the halo structure of the ¹⁷F state is taken into account.
The ISOLDE facility at the CERN PS Booster
1993, Nuclear Inst. and Methods in Physics Research, B
The CERN ISOLDE on-line mass separator facility was reconstructed at the 1 GeV PS Booster and is now being commissioned. Protons in very short high intensity pulses (average current 2 μA) are directed on either one of the targets of the two on-line mass separators. The 60 keV ions from them are fed into a common beam transport system to which most of the experiments will be connected. The facility can supply radioactive beams of about 60 elements from the whole nuclear mass range to a community of more than 250 physicists working in the fields of nuclear, atomic, surface and solid-state physics, astrophysics and nuclear medicine. The most interesting features of the facility will be discussed and a few experiments described to illustrate the extent of the experimental programme. An outlook into future developments such as resonant laser ion sources and plans for post-acceleration of radioactive ions will be given.
The new CERN-ISOLDE on-line mass-separator facility at the PS-Booster
1992, Nuclear Inst. and Methods in Physics Research, B
The ISOLDE on-line isotope separators have been operated since 1967 at the CERN-SC. This 600 MeV proton synchro-cyclotron had to be shut down in December 1990 after 33 years of service and it was decided to move ISOLDE to a new experimental area. The new on-line mass-separator facility is now under construction at the CERN PS-Booster. This accelerator provides an average current of about 2 μA of 1 GeV protons in very short high intensity pulses at low repetition rate. The beam can hit either one of the two target stations, the general purpose separator (GPS), a reconstructed ISOLDE-2 type machine (which can deliver beams simultaneously into three beam lines), and the high resolution separator (HRS), which is essentially the slightly modified ISOLDE-3 separator. The central GPS beam line and the HRS feed a common beam transport system to which most of the experiments will be connected. The new facility will be taken into operation in spring 1992.
