Abstract

Studies were carried out to collimator modelling and dosimetry BNCT of in vitro and in vivo test using MCNP-X code. Collimator modelling performed to obtain neutron beam as required by the International Atomic Energy Agency (IAEA). Dosimetry calculations performed to obtain the results of the dose calculation (dosimetry) in the application of BNCT.  Collimator modelling and dosimetry simulations performed with MCNPX program. Neutron sources used for simulation, namely cyclotrons HM-30, energy 30 MeV, the current is 1.1 mA. Collimator modelling utilizes to program MCNPX covers cells target as beryllium, collimator wall (reflector), moderate, filter, gamma-ray shielding, and aperture. The simulation results of the modelling are Φepi 1.02241x1010 n/cm2 s, Df/Φepi 2.36487x10-11 Gy-cm2/n, Dγ/Φepi 4.68416x10-12 Gy-cm2/n, Φth/Φepi 3.76285x10-01, J/Φepi 8.37678x103. Based on the calculation of the dose rate that has been done, the result that the optimal dose rate at a depth of 1cm.

Abstract

A research of design of double layer collimator using 9Be(p,n) neutron source has been conducted. The research objective is to design a double layer collimator to obtain neutron sources that are compliant with the IAEA standards. The approach to the design of double layer collimator used the MCNPX code. From the research, it was found that the optimum dimensions of a beryllium target are 0.01 mm in length and 9.5 cm in radius. Collimator consists of a D2O and Al moderator, Pb and Ni as a reflector, and Cd and Fe as a thermal and fast neutron filter. The gamma filter used Bi and Pb. The quality neutron beams emitted from the double layer collimator is specified by five parameters: epithermal neutron flux 1 ×109 n/cm2s; fast neutron dose per epithermal neutron flux 5 ×1013 Gy cm2s; gamma dose per epithermal neutron flux 1×1013 Gy cm2s; ratio of the thermal neutron flux of epithermal neutron flux 0; and the ratio of epithermal neutron current to total epithermal neutron 0.54.

Abstract

Film Ag2O telah ditumbuhkan pada top electrode Si/Ti/Pt dengan evaporasi termal. Proses evaporasi dilakukan pada tekanan 2×10-2 mbar dalam atmosfir oksigen sintetis. SEM digunakan untuk menganalisa struktur permukaan film. Top electrode dilekatkan pada chip FG-FET untuk membentuk sebuah sensor gas yang sensitif terhadap H2S. Karakterisasi yang meliputi uji temperatur, konsentrasi, kelembaban dan selektivitas dilakukan untuk mengetahui kehandalan sensor. Hasil karakterisasi menunjukkan bahwa FG-FET berbasis film Ag2O dapat mendeteksi H2S pada konsentrasi rendah dengan temperatur operasi optimum 95°C dalam keadaan kering maupun lembab. Penambahan klaster Fe pada permukaan film Ag2O dapat meningkatkan unjuk kerja sensor yang ditandai dengan peningkatan sinyal keluaran sensor. Keywords:FG-FET, Film Ag2O, Fe,Fungsi Kerja, H2S

Abstract

A Double Layer Beam Shaping Assembly (DLBSA) was designed to produce epithermal neutrons for BNCT purposes. The Monte Carlo N-Particle eXtended program was used as the software to design the DLBSA and phantom. Distribution of epithermal neutron and gamma flux in the DLBSA and phantom and absorbed dose in the phantom were computed using the Particle and Heavy Ion Transport code System program. Testing results of epithermal neutron beam irradiation of the water phantom showed that epithermal neutrons were thermalized and penetrated the phantom up to a depth of 12 cm. The maximum value of the absorbed dose was 2 × 10-3 Gy at a depth of 2 cm in the phantom.

Abstract

Study on magnetic properties of iron sand on the Logending beach sand has been done. The research aims to identify the mineral content and characterization of magnetic properties on the Logending beach sand. The irond sand samples taken from the Logending beach with several lokation. Sand then dried, determined density and magnetic content is separated using a permanen magnet. The iron sand were analyzed using XRD ( X-ray difraction) and characterization of magnetic properties using the VSM (Vibrating sample magnetometer). The research shows that minerals are contained hematit (Fe2O3), with a value of susceptibility is 0.43 x10-6 m3/kg. The main magnetic mineral of iron sand from logending beach is paramagnetic.

Abstract

It have been done analysis high potential mineral contents of sands and sandstone in Banyumas region. Sands and sandstone are taken from mining traditional at rivers and river?s stone grinder place. Sand samples were taken from Tajum, Logawa, Serayu and Klawing river, while sandstone were taken from Banjaran, Logawa and Klawing river?s grinder place. Sand was separate using permanent magnet to disassociated the magnetic and non magnetic mineral content and analyzed by X-ray difraction to reveal the mineral types. The Result indicated that river sand contained 39% magnetic mineral and 61% non magnetic. While identification using X-ray difraction obtained that sand have mineral of complex structured of valuable element such as Fe, Ti, Si and Zn and also rare earth like Y, Ca, Li and La.
