Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Conference Paper Description
In this paper the on going design of the power supply for the beam chopper magnets of a medical synchrotron is presented. The four, series connected beam chopper magnets, which are placed on the extraction line, are used for blanking the beam both during routine operation and for emergency. To let the beam pass the magnets need to be energized with a current, proportional to the beam energy, whose maximum value was calculated to be about 650A. The required current should be reached from zero in less than 260μs and then can be maintained for an arbitrary long time. Finally is should fall back to zero in less than 260μs. The power supply is composed of an high voltage part (2.9kV), which is in charge of the rising and falling current ramp and of a low voltage part (60V) which is in turn responsible for the current flat top.
