Chapter 8: Detector System Component
Description
The primary components making up a Synapse CCD detection system are:
•
CCD Detector Head
•
Power Supply Unit
•
SynerJY Application Software
In addition to the primary components listed above, all Synapse CCD detection systems
are provided with one mechanical shutter and an associated interface cable. A number of
shutter options are available for interfacing to various HORIBA Jobin Yvon
spectrometers.
Synapse CCD Detector Head
All Synapse detectors use high quality scientific grade CCD array formats specifically
designed for spectroscopic applications. Choosing the most appropriate format for your
detection system is dependent on the intended spectroscopic application.
Detector Head Cooling
High-performance thermoelectric cooling allows the detectors to achieve temperatures
better than -70
°
C (203 K) without the use of LN
2,
providing very low dark current, and
allowing for good signal-to-noise ratio and long integration times.
The Synapse detector head employs a multi-stage Peltier cooling device that is thermally
coupled to the CCD array inside an evacuated chamber. Heat is drawn away from the
array’s surface as current is passed through the Peltier device. The heat transfer process
continues in succession thru the Peltier stages to a heat spreader located on the
atmospheric side of the detector, where it is then air-cooled via an accessory fan.
The detector heads can run continuously at their set operating temperature of -70
°
C
(system default setting) without maintenance. It should be noted that air-cooled detector
heads, require freely circulating, ambient room temperature air to cool and maintain the
array’s operating set temperature. Failure to stay within the ambient operating conditions
specified herein may cause an increase in array temperature, resulting in higher dark
current.
Synapse detector heads incorporate a temperature sensor that continuously monitors the
Peltier’s hot side sink temperature. This protective circuitry prevents possible damage to
the array by disabling the cooler power supply when its internal, preset temperature is
exceeded due to faults such as inadvertent restricted airflow. Under such a fault
condition, the TEMP LED located on the rear of the detector will transition from a
GREEN illumination state (indicating that thermoelectric cooling is functioning properly
and has reached its set temperature) to a non-illuminated state (indicating a fault/no
cooling).
