ADSC Area Detector Systems Corporation was founded in 1983 by Ronald Hamlin, Christopher Nielsen and Xuong Nguyen-huu.At the beginning, in 1983, the only product of Area Detector Systems Corporation was Multiwire Area Detector (MWAD), which was the first area detector technology for this company. In total about 50 Multiwire Area Detector (MWAD) were sold worldwide. In 1990 the second generation area detector system, called an Image Plate (IP), was manufactured. From 1990 till middle 1996 it was sold 35 Image Plate systems. From middle 1996 the third generation of area detectors have been developing and manufacturing with using a Charge Coupled Device, or CCD.
ADSC history overview
1983 - Date of the company incorporation. From this date over 50 Multiwire Proportional Counter (MWPC) were manufactured.In 1991 the Image Plate (IP) detector was developed and successfully installed in over than 35 places.
In 1996 the company introduced first CCD (Charge Coupled Device) detector Quantum 1.
In 1997 on the basis of Quantum 1 detector the Quantum 4 detector was developed. This model was very popular for synchrotron radiation source laboratories.
In 2000 the Quantum 210 detector was introduced with larger active detection area, higher resolution and shorter readout time.
In 2001 on the basis of the modular design the three x three Quantum 315 detector was constructed. At the moment this detector represents the high-edge limit of current technologies.

ADSC system components
ADSC detector system consists from a few major components, which are included into standard set. These hardware and software is enough to interface the detector to a beam line. Next pictures are based on official picture of ADSC Quantum 315r detector set.
|
The ADSC Quantum 315r detector itself. Generally speaking it's quite big piece of scientific equipment. With 315 X 315 mm active area the total size is 41 X 46 X 92 cm and a total weight is 141 kg. Other detectors are a bit smaller and lighter with total weight of about 48 and 54 kg for Quantum 4r and Quantum 210r, respectively. |
Other equipment includes:
- Highly efficient dry vacuum pump for maintain vacuum inside detector.
- Water Chillier, provides backup for the thermo-electric cooling in the modules
- Power control rack. Heavy duty steel rack for protected power distribution for all system components.
- Data Control Rack. Heavy duty steel rack for data acquisition and processing which includes separate computes for each detector modules (four or nine) and Raid Array for a total capacity of 2 Tera Bytes
ADSC control software
Quantum CCD detectors are supplied with ADSC software package. ADSC software has modular design, which allowing use independent process via TCP/IP network with central Graphics User Interface (GUI) control. ADSC software with Graphics User Interface allow to make simple, safe control of data collection with estimation of the full data collection time and display collected images.ADSC Contacts
