Following the Russian invasion of Ukraine, EU enlargement has regained prominence on the EU agenda. I examine the politicisation of enlargement and arguments for and against enlargement in two debates in the European parliament conducted in November 2023. This is done with a postfunctionalist outlook, expecting that polarisation on the subject will shape along the identity axis. I find that the two debates lack polarisation and can thus not be seen as very politicized. In accordance with postfunctionalist integration theory, I do however note that most traditional and authoritarian parties oppose enlargement. Previous research shows that a member of the European parliament’s nationality also affects positions on enlargement, in combination with the cultural axis. When also taking this into consideration, the understanding of what shapes opinions on enlargement is refined.  The argumentation analysis of the debates shows that opinions that favor enlargement in the debates often stem from a geopolitical urge of positioning the EU against Russia. Opinions that argue against enlargement are mostly concerned about the own country’s payments to the EU budget. This finding leads to a suggestion that more research should be done on how the status as net contributor or net beneficiary to the EU budget shapes opinions on enlargement.

E1039/SpinQuest, a transversely-polarized Drell-Yan experiment at Fermilab, plans to use the 120 GeV proton beam and polarized NH3 and ND3 cryogenic targets to study azimuthal asymmetries in dimuon production to extract the magnitude as well as sign of the sea quarks Sivers functions. The SpinQuest spectrometer is optimized to detect oppositely-charged muons with a series of tracking chambers and hodoscope stations. The scope of this manuscript is to highlight the physics goals and the experimental setup with a focus on the ongoing debugging and training of one of the tracking systems, mainly drift chambers, as preparation for the upcoming commissioning and production run-periods. This work is supported in part by the US DOE contract number DE-FG02-07ER41528. Key words: Drell-Yan, Fermilab, SpinQuest, Polarization, Tracking, Drift Chambers

yes / This paper presents a compact-size, low-cost smart antenna with electronically switchable radiation patterns, and reconfigurable polarizations. This antenna can be dynamically switched to realize three different polarizations including two orthogonal linear polarizations and one diagonally linear polarization. By closely placing several electronically reconfigurable parasitic elements around the driven antenna, the beam switching can be achieved in any of the three polarization states. In this design, a polarization reconfigurable square patch antenna with a simple feeding network is used as the driven element. The parasitic element is composed of a printed dipole with a PIN diode. Using different combinations of PIN diode ON/OFF states, the radiation pattern can be switched toward different directions to cover an angle range of 0◦ to 360◦ in the azimuth plane. The concept is confirmed by a series of measurements. This smart antenna has the advantages of compact size, low cost, low power consumption, reconfigurable polarizations, and beams.
