The Area Density Resolution of 11MeV Low-energy Proton Radiography Using Magnetic Lens System | |
|
||
| The low-energy proton radiography (PRAD) based on the magnetic lens imaging system is an imaging technique suited for the diagnosis of thin objects. According to the theoretical analysis, for objects of small thicknesses, the contrast of the low-energy PRAD result is superior to that of the high-energy PRAD. Proceeding from the imaging principle, the influence of the collimator angle of the magnetic lens system on the area density resolving power is investigated. The PRAD results of aluminum foil objects on the 11MeV PRAD beamline at the China Academy of Engineering Physics (CAEP) are also demonstrated. The experimental results show that, by setting the collimator angle appropriately, this 11MeV PRAD beamline was able to radiograph objects of area density less than 2.7×10'2 g/cm2. | ||
