The phrase "a detector with a" is correct and usable in written English.
It can be used when describing a specific type of detector that has a particular feature or capability.
Example: "The experiment requires a detector with a high sensitivity to measure the faint signals accurately."
Alternatives: "a detector featuring a" or "a detector equipped with a".
The light from the two telescopes was merged into a detector with a fine grid of wires.
To detect the spin coming out of silicon, Appelbaum and his colleagues made a detector with a unique layered structure: a nickel-iron layer on top of a copper layer, which is deposited on a silicon substrate.
As the energy of radiation is usually unknown in such situations, a detector with a weak energy dependence of its response to dose would be ideal.
ZEPLIN I, a detector with a 4 kg fiducial mass with a background discrimination based on Pulse Shape Analysis, is already underground and starting operation.
A detector with a very specific design using liquid Xenon (LXe) in the scintillation mode is studied for Positron Emission Tomography (PET) of small animals.
A detector with a gaseous active media equipped with gas electron multiplier (GEM) technique will be employed to measure tracks of charged particles at forward direction in order to achieve a high momentum resolution.
The goal is to develop a detector with an energy resolution of 0.1% for 1 20 MeV neutrons with an efficiency of 1%.
In cosmic-ray muon radiography, a detector with an area on the order of square meters is placed so that it is imaging a volume that is higher in elevation adjacent to the detector.
Moreover, those models can be used to investigate edge effects and performance of a detector with an arbitrary pattern of active elements and dead areas, in order to study systems with more multianode PMTs or SiPM array modules.
No-one has put a detector with such a sensitivity - using the technology developed at Cern/LHC - in space before".
The Hubble Space Telescope has a CCD detector with a 1,600 × 1,600 pixel array.
