Analisis Kualitas Keluaran Harian Dari Pencacahan Dan Energi Berkas Elektron Sumber Akselerator Linier

---

One of the modalities used in radiotherapy is Linac. Linac radiotherapy devices
often experience instability output, one of the irradiation errors with Linac can
occur because the radiation beam that comes out is not good energy.
Determination of the correction factor and linearity is important to analyze the
charge output of the electron energy emitted by Linac's modality to observe the
stability of the emitted charge. Linac works on the principle of accelerating
electrons gun until the required energy is reached. Then the electron beam is
passed on the scattering foil so that the intensity of the resulting beam is uniform.
This study uses Electron Linear Accelerator Electron beam daily output data with
a 10 cm × 10 cm applicator, 100 cm SSD, 0.125 cc cylindrical ionization detector
PTW type 31010 Semiflek and uses a slab solid phantom with energy variations
of 6 MeV, 8 MeV, 10 MeV, 12 MeV and 15 MeV. The measurement results are
calculated using the IAEA TRS 398 protocol. The result of linearity correction
factor of 96.87% which shows the stability value of the electron beam load output
is good energy, and the results of the correction factor show the enumeration
values of each energy 6 MeV, 8 MeV, 10 MeV, 12 MeV and 15 MeV namely
0.030342129 nC, 0.03034 nC, 0.03034 nC, 0.03034 nC and 0.03034 nC values
respectively still within the tolerance range of ± 1 according to TRS 398. The
correction factor that has been obtained is used as a parameter in calculating the
absorbance dose to the maximum.
Keywords: Linac, Electron, Correction Factor, TRS 398
