	While most of the beam time of the cyclotron is used for proton therapy of ocular melanomas, an increasing amount of beam time is used for experiments. In response to a growing demand on time structures a new pulse suppressor was developed. This was necessary as our cyclotron was originally designed for heavy ions, thus limiting us to repetition rates of 75 kHz for light ions. The pulse suppression is now accomplished completely on the low-energy side, making the pulse suppressor on the high energy side, which was needed for single pulses, superfluous. With this new pulse suppressor the repetition rate of the pulse may be varied from 2 MHz down to 1 Hz or less. The pulse length can be freely chosen from a quasi-continuous beam to single pulses with a pulse width less than 1 ns. The pulses are measured either with a specially developed Faraday cup or non-destructively with a pick-up. The extraction of single pulses surveys very precisely if single turn extraction is achieved. The set-up of the pulse suppressor, measurements on the time structures for various beams and examples of their experimental use will be presented.

While most of the beam time of the cyclotron is used for proton therapy of ocular melanomas, an increasing amount of beam time is used for experiments. In response to a growing demand on time structures a new pulse suppressor was developed. This was necessary as our cyclotron was originally designed for heavy ions, thus limiting us to repetition rates of 75 kHz for light ions. The pulse suppression is now accomplished completely on the low-energy side, making the pulse suppressor on the high energy side, which was needed for single pulses, superfluous. With this new pulse suppressor the repetition rate of the pulse may be varied from 2 MHz down to 1 Hz or less. The pulse length can be freely chosen from a quasi-continuous beam to single pulses with a pulse width less than 1 ns. The pulses are measured either with a specially developed Faraday cup or non-destructively with a pick-up. The extraction of single pulses surveys very precisely if single turn extraction is achieved. The set-up of the pulse suppressor, measurements on the time structures for various beams and examples of their experimental use will be presented.
