Lorentz shift measurements in heavily irradiated silicon detectors in high magnetic fields

Wim de Boer, Karl-Heinz Hoffmann, Andreas Sabellek +4

An external magnetic field exerts a Lorentz force on drifting electric charges inside a silicon strip sensor and thus shifts the cluster position of the collected charge. The shift…

Study of leakage currents in pCVD diamonds as function of the magnetic field

S. Müller, W. deBoer, M. Schneider +5

pCVD diamond sensors are regularly used as beam loss monitors in accelerators by measuring the ionization of the lost particles. In the past these beam loss monitors showed sudden…

New limit on the present temporal variation of the fine structure constant

E. Peik, B. Lipphardt, H. Schnatz +3

The comparison of different atomic transition frequencies over time can be used to determine the present value of the temporal derivative of the fine structure constant alpha in a…

Lorentz angle measurements in irradiated silicon detectors between 77 K and 300 K

W. de Boer, V. Bartsch, J. Bol +7

Future experiments are using silicon detectors in a high radiation environment and in high magnetic fields. The radiation tolerance of silicon improves by cooling it to temperature…

First experiments with a 100 period superconductive undulator with a period length of 3.8 mm

M. Fritz, T. Hezel, M. Homscheidt +10

A prototype of a novel superconductive undulator with a period length of 3.8 mm is described. The undulator is 100 periods long. In the first tests described in this paper the undu…

A superconductive undulator with period length of 3.8 mm

T. Hezel, B. Krevet, H. O. Moser +3

During the last years several attempts were undertaken to decrease the period length of undulators to the mm range. In this paper, a novel type of an in-vacuum undulator is describ…
