A new software for MCA4A including new firmware can be downloaded from the MCA4 support page. It enables to use the SCA1 and SCA2 from the PHA part to be used as STOP1 and STOP2 inputs for MCS mode. This is especially usefull for Mossbauer applications as it reduces background by selecting only the 14.4 keV gamma line as inputs for the multichannel scaling.

The TA8008 octal timing amplifier comprises a common power supply casing that is populated with a user selectable choice of 8 amplifier modules AM8000.

 

The pool of available AM8000 fast timing amplifiers conists of 3 basic type families:

- AM81xx low noise, high bandwidth

- AM82xx high bandwidth, high gain

- AM83xx very low loise

 

Each AM83xx model is also available with a bandwidth limited (BWL) option which further reduces the noise floor.

The Model MCS8A is a 80 ps per time bin, multiple-event time digitizer (TDC) with 1 start and up to 8 stop inputs. It can be used in ultra-fast Multiscaler/TOF systems, in Time-of-Flight massspectrometry and timeresolved single ion- or photon counting. Pulse-width evaluation with 80 ps precision enables the user to calculate the area, the pulse height of the detector pulse but also if multiple events have occured – multiple events have a broader pulse width than single pulses. In operation the sweep is started by a usersupplied start (trigger) pulse. Then subsequent events detected at the stop inputs are recorded, each in a specific time bin corresponding to the time of arrival relative to the start pulse. Compared to non-multi-hit devices, the MCS8A can evaluate stop events at a rate of 12.5 GHz state changes/sec, in the pulse width mode at 6.25 GHz. The USB 3.0 interface enables a permanent throughput of 240 MB/s. A version with only seven stop inputs (MCS8) is already deliverable.

The 2155 Pent CFT is a five-fold fully dc-coupled constant fraction discriminator with a dynamic range of up to 500:1. Selected fraction and three operating modes provide optimum time resolution for any detector types and applications. The unit accepts negative polarity pulses to the 50Ω terminated dc-coupled inputs. On customer request the module can be modified to accept positive input signals. Output signals are generated whenever the input signal exceeds the selected threshold set by a front panel potentiometer (T).
