Model 2000/2100 Bin/Power Supply

Model 2000/2100 Bin/Power Supply

Description

The CANBERRA Models 2000 and 2100 Bin/Power Supplies provide mounting space and power sources for up to 12 standard Nuclear Instrument Modules (NIM) conforming to DOE/ER-0457T. Multiple width NIM modules are also accommodated in any combination up to a total of 12 single widths. Modern circuit design and thermal management allow a high level of performance to be delivered in an adjustment-free, low-profile package that allows easy access to the NIM rear panels.

Connectors for each module position provide the standard NIM power supply voltages of ±6*, ±12 and ±24 V dc, and 117 V ac. Up to 150 W of total dc power is available to a balanced load at ambient temperatures up to 50 °C, with derating up to 60 °C. The power supply is EMI filtered, short-circuit proof, thermally protected, tightly regulated and exceptionally stable. It includes over-voltage protection for the ±6 V supplies*. In addition, the ac inrush current is controlled to reduce transients in sensitive systems as well as to enhance reliability.

The control panel includes an on/off switch, a power monitor lamp, voltage test points and a temperature warning lamp which indicates temperatures approaching the design limit of the power supply.

The Bin is preconfigured at the factory for the standard line power of the destination country. However, an externally accessible line-entry module facilitates selection of 100, 120, 230 or 240 V ac nominal input power.

Model 3002D 0-3 kV H.V. Power Supply

Model 3002D 0-3 kV H.V. Power Supply

Description

The CANBERRA Model 3002D is a NIM Bin compatible high voltage power supply designed for operation with essentially all types of nuclear radiation detectors. Particularly well-suited for use with scintillation detectors, the standard double-width NIM module provides a well regulated output up to 10 mA at 0 to ±3000 V dc.

A recessed switch on the bottom panel is used to select either 115 or 230 V ac input power furnished through a power line cord and connector. The Model 3002D can also be operated outside the NIM Bin from any ac power receptacle, since it requires no power from the Bin. The power supply will withstand any overload or direct output short-circuit for an indefinite period of time and provide normal output automatically upon removal of the fault.


Output voltage is continuously adjustable by means of the calibrated front panel control over the full range from 0 to ±3000 V. The output voltage can also be controlled over its full range by application of an external input dc level of 0 to -5 V through a rear panel BNC connector.

A 3-1/2 digit liquid crystal display meter measures output voltage with a resolution of 10 V, and output current with a resolution of 10 mA. A polarity reversal switch provides selection of positive or negative output polarity. To prevent inadvertent polarity reversal, the switch is top panel mounted and screwdriver activated. In addition, the setting of the polarity selector switch is indicated by illumination of a front panel LED which can be previewed in the STANDBY mode.

Model 3102D 0-2 kV H.V. Power Supply

Model 3102D 0-2 kV H.V. Power Supply

Description

The CANBERRA Model 3102D High Voltage Power Supply is a single-width NIM module designed primarily for use with photomultiplier and electron multiplier tubes. But it can be used with any detector requiring a bias voltage up to 2000 V and a current level of 1 mA or less.

The 3102D allows the user to select from two continuously adjustable outputs, one ranging from ±15 to ±2000 V dc and the other from ±1.5 to ±200 V dc. The output voltage is measured and displayed by a three-digit voltmeter. In addition, this unit allows the user to select the output voltage polarity with an internal control.

The 3102D can withstand any overload or short circuit for an indefinite period of time. It can be set using an internal jumper to allow for a manual reset or an automatic reset when the fault condition is removed.

The 3102D features an output rise time of five seconds to protect preamplifiers and detectors from excessive surge currents while charging.

Model 3106D 0-6 kV H.V. Power Supply

Description

The CANBERRA Model 3106D is a NIM high voltage power supply designed primarily for operation with semiconductor detectors. It is particularly well suited for use with high resolution detector systems. By design, the 3106D will accommodate all types of detectors requiring up to 6 kV bias and up to 300 μA of current.

The output voltage is continuously adjustable from ±30 V dc to ±6000 V dc. For low voltage detectors, a secondary output having a range of ±3 V to ±600 V is available. A three-digit volt meter measures and displays the output voltage with a resolution of 10 volts on the normal output and 1 volt on the secondary output. Polarity is selected internally.

The Model 3106D will withstand any overload or short circuit condition for an indefinite period of time. An inhibit input is available for remote shut down of the 3106D. The unit can be programmed by an internal jumper either to resume normal operation after removal of the fault or the inhibit or to require a manual reset.

The 3106D’s output rise time of 5 seconds protects preamplifiers and detectors from excessive surge currents while charging.

Model 9641 ICB Programmable H.V. Power Supply

Model 9641 ICB Programmable H.V. Power Supply

Description

The CANBERRA Model 9641 High Voltage Power Supply is a single-width NIM family member of the Instrument Control Bus (ICB) line of programmable front end electronics. It has been designed primarily for use with photomultiplier and electron multiplier tubes. The Model 9641 accepts programming information over the 8-bit wide CANBERRA bus standard called the ICB. By design, the Model 9641 will accommodate any detector requiring a bias voltage up to 2000 V and a current level of 1 mA or less.

The Model 9641 allows the user to select from two outputs, one ranging from ±15 to ±2000 V dc and the other derived from the first but attenuated by a factor of 10 giving ±1.5 to ±200 V dc. A 20-segment bar graph displays the output voltage. In addition, this unit allows the user to select the output voltage polarity with an internal control.

The Model 9641 can withstand any overload or short circuit for an indefinite period of time. The unit can be programmed to either resume normal operations after removal of the fault or to require a programmed reset command.

An INHIBIT input is available for remote shutdown of the Model 9641. The unit can be programmed to either resume operation upon removal of the INHIBIT signal or to require a programmed reset command.

ICB NIMs connect to this bus via a host module such as the Model 556A Acquisition Interface Module (AIM) as part of a hierarchy of networked acquisition and control managed by a Genie family computing platform.

Most adjustments are made through the graphical user interface of the Genie software environments. Equivalent batch procedure commands are also available in the environments. All ICB NIM parameters are stored in the single data file structure of the Genie family, allowing verification of correct set up from one experiment to the next.

All ICB NIMs feature a characteristic READY LED to indicate operational status.
