“…All cables were terminated with a 50 ohm resistor. As for the discriminator, the one we had was a little bit different from [13]-we did not have peak sensing circuitry. Also, the preamplifier was Analog Devices AD8009 instead of AD9623 and the discriminator was AD96687 instead of MAX9687.…”

“…Finally, we examined the consequences of introducing the air gap between the fibre end and the photomultiplier glass window. The time resolution was determined by creating a histogram of the pulse detection times at the output of the leading edge discriminator [13] and subsequent examination of the spread of the obtained time distribution. Since the simulations were performed in accordance with the building of a new scintillating fibre detector for the CERN-COMPASS experiment [14], we used particular values of parameters for the scintillating fibres, the photomultiplier and the discriminator, obtained from manufacturer-supplied datasheets [15,16].…”

This paper presents the results of a Monte Carlo study of the time resolution of a scintillating fibre detector and analyses its dependence on the various aspects of detector construction. The estimations of the theoretical time resolutions for detectors with different numbers of fibre layers and different types of acrylic-based fibre coatings are presented. The method is suggested to decrease the rate counting effects encountered in high rate applications. It has been observed that for dual cladding fibres with a fluorinated polymer used for the outer cladding, the most significant factor contributing to the time resolution is the number of fibre layers, with the fibre coating being the marginal one. Another observation shows that the introduction of a gap between the fibre and the photomultiplier glass window allows the reduction of the number of photoelectrons by 25% with only a slight decrease in the time resolution, which may be helpful in decreasing the pulse pile-up effects and the photomultiplier gain, commonly observed under high rate conditions.

“…This is mainly due to the grazing effect; a particle hitting a plane not perpendicularly to the plane, crosses several scintillator columns. The cross talk at different levels adds to this phenomenon [GOR00]. However, in the simulation, only one specific column fires.…”

“…Thus to simulate these effects, we have added, with a probability of 20−28%, to every true Monte-Carlo hit in the plane a firing in the neighbouring columns, and larger cluster of hits with smaller probability. The photomultipliers cross-talk has also to be taken into account and, due to their geometrical disposition, we have added to every true hit a 2−3% extra hit at a column distance of ∆n = ±4 [GOR00]. This procedure introduces some diffuseness to the simulated hit position.…”

A new scintillating fiber detector has been built for the COMPASS experiment at CERN, in order to improve detection efficiency of high energy muons scattered at small angles with respect to the beam. We present the description of construction work, as well as performance study based on data collected during 2006 and 2007 data taking periods. Special attention is given to a new technology that we used for connecting clear fibers (Kuraray CLEAR-PSMJ) with the scintillating ones (Kuraray SCSF-78MJ) by a radiation hard UV-cured medical glue Loctite 3081. Results of series of measurements are presented, which were made in order to determine radiation hardness, tensile strength and transmission loss of the joints.
