Ion source and LEBT of KAHVELab proton beamline

The KAHVE Laboratory, at Bo\u{g}azi\c{c}i University, Istanbul, Turkey is home to an educational proton linac project. The proton beam will originate from a 20 keV H+ source and will be delivered to a two module Radio Frequency Quadrupole (RFQ) operating at 800 MHz via a low energy beam transport (LEBT) line. Currently, the design phase being over, commissioning and stability tests are ongoing for the proton beamline which is already produced and installed except the RFQ which is being manufactured. This work summarizes the design, production and test phases of the ion source and LEBT line components

The acrocallosal syndrome in a Turkish boy.

A 6 month old Turkish boy with the acrocallosal syndrome is reported. The patient, born to consanguineous, healthy parents, presented with macrocephaly, a prominent forehead, hypertelorism, polydactyly of the fingers and toes, severe motor and mental retardation, hypotonia, and absence of the corpus callosum. The mode of inheritance is discussed and our case is compared with previously reported cases of the syndrome

The State’s Changing Role Regarding the Kurdish Question of Turkey: From Consistent Tutelage to Volatile Securitization

Disappearance of the established security paradigm of Kemalist state has not helped to create strong institutions and legal-bureaucratic structures that are supposed to prevent a certain political elite to dominate the political system and criminalize its adversaries by security reasons. Instead, survival concerns and political will of the Justice and Development Party (AKP) has become replacement of the established paradigm. This has created a systemic crisis. On the one hand, the AKP has played the role of a regular political party, which is supposed to have equal rights and privileges with other players in the game. On the other hand, the AKP has been the tutelary actor that determines what national security is and who threatens national security. As a result of this picture, the AKP has exploited its monopoly over securitization to eliminate the criticisms of the opposition groups. Therefore, any political party or political group has not been viewed as a national security threat only if it has not threatened the political survival of the AKP. Such a crisis has also affected the AKP’s approach toward the Kurdish question. Unlike the established paradigm’s allergy toward the political demands of Kurds due to its commitment to nation-state principle, the AKP’s fluctuated policy toward the Kurds resembles to a political party’s survival strategy rather than a policy stemming from a consistent national security paradigm
