    Development of diagnostic and manipulation systems for space-charge dominated electron beams and confined electron plasmas in ELTRAP

    No full text
    Modifications have been implemented in the Penning-Malmberg device ELTRAP aimed at performing studies on the dynamics of space-charge dominated nanosecond electron bunches traveling along the magnetic field. In particular, a Thomson backscattering apparatus has been developed where an infrared (IR) laser pulse collides with the bunched electron beam. The frequency-shifted backscattered radiation, acquired by means of a photomultiplier (PMT), can be exploited to evaluate information on energy, energy spread and density of the bunch. The achievable sensitivity of the diagnostics has been estimated, and valuable information on the main parameters affecting the signal-to-noise (S/N) ratio has been obtained [B. Paroli, F. Cavaliere, M. Cavenago, F. De Luca, M. Ikram, G. Maero, C. Marini, R. Pozzoli, and M. Romé, JINST 7, P01008 (2012)]. A series of upgrades are under way, aimed at increasing the S/N ratio through the use of a new laser for the electron source, the insertion of a stray light shield, and the optimization of the detection electronics. Moreover, electromagnetic simulations relevant to the design and implementation of a microwave heating system are presented. The generation of an electron plasma in ELTRAP by means of a low-power radio frequency (RF) drive in the MHz range applied on one of the trap electrodes and under ultra-high vacuum (UHV) conditions has previously been demonstrated [B. Paroli, F. De Luca, G. Maero, F. Pozzoli, and M. Romé, Plasma Sources Sci. Technol. 19, 045013 (2010)]. The new heating system will allow the extension of the RF studies to the GHz range and in particular the production of a more energetic electron plasma via cyclotron resonant excitation

    This thesis presents a strain mapping in nanostructure Al2O3/TiO2 ceramic coatings on metallic Titanium substrates by synchrotron radiation. The mapping is obtained under various boundary conditions (tension/compression loads, four-point bending, etc.) and is accomplished using high energy (deeply penetrating) synchrotron white radiation with photon energies up to 200 keV to perform high precision x-ray diffraction on small volumes (1 µm to a few cm), which are then integrated into high resolution 3D maps of the strain fields. Strain mapping in conventional micro-size ceramic coatings are performed for comparison. The underlining structural and functional parameters in processing of these coatings, which result in dramatic improvements in their performance, are discussed. The thesis also presents mechanical properties such as elastic modulus, yield strength, etc., which are deduced from energy dispersive X-ray diffraction (EDXRD) strain mapping in conjunction with modeling.M.S.Includes bibliographical referencesby Nazia Ikram Ahmed

    No full text
    Kajian ini bertujuan untuk menganalisis pendekatan pendidikan yang dibawa oleh IKRAM Malaysia melalui analisis kandungan dokumen utama, penulisan watak dan laporan program pendidikan dari tahun 2020 hingga 2023. Lima tema utama telah dikenal pasti melalui analisis sepuluh sumber utama. Pertama, pendidikan IKRAM berteraskan konsep pendidikan Islam holistik yang menggabungkan aspek intelek, rohani, emosi dan sosial. Kedua, peranan guru dilihat bukan hanya sebagai pendidik, tetapi sebagai murabbi dan pemimpin nilai yang berperanan membentuk legitimasi pelajar. Ketiga, pendidikan dijadikan sebagai instrumen dakwah dan islah sosial melalui program kemasyarakatan khususnya dalam kalangan masyarakat B40. Keempat, sejak 2022, akan wujud integrasi nilai-nilai Madani seperti belas kasihan, hormat-menghormati dan amanah dalam kerangka pendidikan IKRAM, selaras dengan keperluan semasa masyarakat Malaysia. Kelima, pasca-pandemik menyaksikan peralihan dalam strategi ke arah pendidikan digital dan hibrid yang lebih fleksibel dan mampan. Kajian ini merumuskan bahawa pendekatan pendidikan IKRAM adalah dinamik, responsif dan berasaskan nilai, menjadikannya model pendidikan Islam kontemporari yang holistik dan relevan dengan kehendak zaman
