The Chamber Adapter is an external electronic bias supply for the Piranha X-ray multimeter and Cobia. The Chamber Adapter makes it possible to connect ion chambers with a Lemo connector to the external input of the Piranha. The Chamber Adapter is primarily designed for CT and mammography applications but can be used for other applications.
Chamber Adapter. To charge the Chamber Adapter: 1. Turn off and disconnect the Chamber Adapter from the Piranha. 2. Connect the Piranha power supply to the Chamber Adapter and make sure that the main switch is in the off position and the Charge LED is on.
NOTE: This can only be done with Piranha. 1. Connect the Chamber Adapter to your Piranha. You don't need to power it on or have an ion chamber connected. 2. Connect the Piranha to the computer with an USB cable (recommended). If you use Bluetooth, make sure that the Piranha is fully charged before you start.

In the example picture above, we have a Piranha and a CT ion chamber, "DCT10(PBCA)". "PBCA" is the chamber adapter identification information. This information is locked at the factory during manufacturing and cannot be changed. If you click on a detector to the left, the available calibrations are shown to the right.

Select type of ion chamber you want to add from the drop-down list. Any chamber type can be used with the Chamber Adapter that has the (PBCA) extension. If you can't find your specific chamber, there are three generic chamber types you can choose which are based on the chamber volume.

13. Quit the Detector Manager when the new data is stored in the device. As soon as you start Ocean 2014 or the QABrowser and use the new ion chamber with your Piranha, the new calibration information will be available for use. Chamber Adapter User's Manual 2019-10-14/1.6A...
When the Piranha and the Chamber Adapter are connected only the available and suitable ion chambers are shown (see picture below). If your Chamber Adapter is programmed to be used with more than one ion chamber, you may see more than one selection in the drop-down list.

6. Select the ion chamber you want to use and click OK. 7. The measurement is activated and you can start to make exposures. You can check which ion chambers are stored in your Chamber Adapter by clicking on the Meter Info button on the Ribbon bar: 2019-10-14/1.6A...
5. The detector selection will appear. Your particular detector selection picture may be different than those shown in this manual, depending on the number of ion chambers stored in your Chamber Adapter. If you use only one ion chamber with your Chamber Adapter, your detector selection screen will look like the one below: The serial number is shown on the bottom right of the screen.

Hirose ST40 for the Piranha Dimensions: 120 x 60 x 35 mm Weight: 240 g Operating temperature: 15 - 30 °C and relative humidity: at <80 % relative humidity Storage temperature: -10 °C to +50 °C Chamber Adapter User's Manual 2019-10-14/1.6A...
I get the wrong time when measuring short times? The Chamber Adapter is not suitable for time measurements, especially if exposure time is short. The bandwidth is only 10 Hz. What is the small hole at the same side where I connect the chamber used for? It is used when the Chamber Adapter is calibrated.

Do you have a question about the Chamber Adapter and is the answer not in the manual?
