Electron beam (E-Beam) irradiation is a form of ionizing energy that is characterized by its low penetration and high-dosage rates. The beam – a concentrated, highly charged stream of electrons – is generated by accelerators capable of producing continuous or pulsed beams. As the product/material being sterilized passes the E-Beam, energy. the complete linac system. The first electron beam of ~ mA was extracted in May’ The Gun Filament power was W and the Gun Modulator was operated at 50 kV with pulse width of 10 msec and PRF of 15 Hz. A forward RF power of ~ MW peak was fed to the linac and the reflected power was ~ kW. Energy analysis of the electron beam.
Electron-beam processing or electron irradiation (EBI) is a process that involves using electrons, usually of high energy, to treat an object for a variety of purposes. This may take place under elevated temperatures and nitrogen atmosphere. Possible uses for electron irradiation include sterilization and cross-linking of polymers.. Electron energies typically vary from the keV to MeV range. The electron source can deliver a pulsed electron beam of up to mA with an output energy of 90 keV. This design is well proven and already used at three injector systems build by ACCEL . Figure 2: 3D model of the 10 MeV structure including the bunching system. The 10 MeV structure as well as the bunching section can be seen in Figure 2.
EXPERIMENTAL STUDY OF EFFECTS ELECTRON IRRADIATION FROM 20 keV TO 1 MeV ON A POLYETHYLENE TEFEPIECRALATE CAPACITOR-TYPE METEOROID DETECTOR By Thomas G. James, Harry H. Heyson, and Clifford S. Frank Langley Research Center SUMMARY A capacitor-type meteoroid detector was irradiated with low-energy elec trons. Under irradiation, this detector produced . LPR-4 type linear electron accelerator (I.I. accelerator). This accelerator produces an electron beam with an average energy of 3–6 MeV, with either single electron pulses or a continuous train of pulses at a frequency of 50, 25, or Hz .

Assuming % efficiency, a 1-kW beam can irradiate kg of product with a dose of 10 kGy/h. The efficiency of electron accelerators is higher than that of gamma sources because the electron beam can be directed at the product, whereas the gamma sources emit radiation Cited by: the same manufacturing rate as a 10 MeV, 50 kW electron beam, the EB source for X-ray generation will have kW of power, but will provide signi ﬁ - cantly greater depth of penetration.

When we travel. At 35 MeV and zero degrees with respect to the beam direction the dose rate is approximately: R0 = 1 x rads/h/kW (1 x Sv/h) at one metre times 40 kW of electron-beam power to produce a photon field of 4 7x 10 rads/h (4 x Sv/h) at one metre. At 90º the radiation dose rate is: R90 = rads/h/kW.

Depth of 50% dose in cm (R50) is multiplied by a constant (C4). Product is mean energy of the electron (Eo) beam stated in MeV at phantom surface Eo = C4R50 Practical range (Er) in cm of an electron beam in tissue Er = MeV/2 Depth of the 80% isodose line in cm in tissue 80% isodose = MeV/3 Depth of the 90% isodose line in cm in tissue 90%.The efficiency of the electron-to-X ray conversion process is relatively poor and depends on the material of the converter plate and the energy of the electron beam.
If Pb and a 5-MeV electron beam are used the efficiency is approximately 8%, while of the electron energy is converted to by: 5. In general, a kW beam has 10 times the throughput capability of a 15 kW beam. To calculate the power of an accelerator, we can use the following equation: Power = Current x Energy.
Therefore, if an accelerator is operating at 5 MeV, and the maximum current capability is 30 mA, then it is a kW .
