A Glaser magnet, having bell-shaped distribution of axial field, is often used to focus charged particle beams in the low energy section of accelerators and in many other devices. The transfer matrix of a Glaser magnet available in the literature is only for a rotationally axisymmetric beam. The objective of this paper is to obtain the 4D transfer matrix of a Glaser magnet for a non-axisymmetric beam having different emittances in the two transverse planes. Starting from the Hamiltonian of a single particle motion we have obtained the 4×4 linear transfer matrix of the Glaser magnet in symplectic form. The matrix so derived has been used to estimate the beam envelope through a Glaser magnet using the well known sigma matrix method. We have also studied the emittance growth that results from the coupling between the two transverse planes as the beam passes through the Glaser magnet.

Die Gläser bestehen aus Polycarbonat, sind bis zu 100 Grad Celsius befüllbar und tiefkühlgeeignet, sollten allerdings weder in die Spülmaschine noch in die Mikrowelle gestellt werden. Wer die Gläser auch während der Fahrt – zum Beispiel als Mitfahrer auf der Rücksitzbank – nutzen möchte, rüstet sie mit den passenden Deckeln aus und verhindert so, dass das Getränk herausschwappt. Für die Nutzung vor dem Reisemobil bietet Silwy außerdem einen Campingtisch mit integrierter Metallschicht an. Die Gläser gibt es in acht verschiedenfarbigen Ausführungen, eine gesamte Geschirrkollektion ist in Planung. Ein Set bestehend aus zwei Gläsern und zwei Untersetzern kostet exklusive 29,95 Euro.

Native son of New York State, Andrew Yurman-Glaser (Broad City; Magnet’s The Wrath, Friday Night Sh*w; UCB’s Mermaids; Upstate) joins us in the studio to talk about improvising, coaching, and the dynamics of a good team. Host Louis Kornfeld dives in by asking, “Do you remember when you got good at improv?” Humility abounds as Andrew tells of getting his improv start in college and how he’s grown over the last nine years in NYC.  He goes on to compare his Megawatt team, The Wrath, to an orchestra and tries to shed some light on how a team maintains their integrity over the course of years. Louis asks if Andrew plays differently on Lloyd Night, Harold Night, Megawatt, or Friday Night Sh*w and Andrew talks about when shows feel the most successful. Hear Louis’ favorite things about how Andrew improvises, Andrew’s thoughts on the importance of listening, and of course, how improv makes you a better person. Plus! Did Andrew’s parents watch him play a masturbator on Broad City? Does Louis like giving notes?? Has this episode been recorded in front of a group of prisoners???  Find out the answers to all of these questions and more on Episode #48.

Miami Arts Studio is a brand new mega magnet program in Miami-Dade County. The incoming 6 and 9th grade students come from all over Miami-Dade County with the vision of becoming leaders in their hopeful magnet strand. For the first year we had over 1,000 applicants for 300+ seats during the 2015-2016 recruitment period. The audition process is a talent-based process, with the exception of a few strands that are interview and portfolio driven. Learn more.

Was nervt im Reisemobil am meisten? Wahrscheinlich klapperndes Geschirr, das während der Fahrt in den Schränken hin und her rutscht. Das Unternehmen maglassX aus Passau hat mit seinen Silwy-Gläsern für dieses Problem jetzt die Lösung gefunden: Ein Magnet im Unterboden hält das Glas auf dem dazu passenden Untersetzer mit integriertem Gegenpol fest. Die Untersetzer stattet maglassX mit einer rutschfesten Haftschicht aus. Die hält das Glas dort, wo es der Reisemobilist hinstellt. Im Test bewegte sich das Glas selbst bei flotten Kurvendurchfahrten und bei starkem Bremsen nicht auf dem Untersetzer hin und her. Sollte die Haftkraft des Untersetzers einmal schwinden, genügt es, ihn unter fließendem Wasser zu reinigen.

Since the discovery that MnOAc acts as a single-molecule magnet (SMM), an increasing number of transition metal complexes have been demonstrated to behave as SMMs. The signature of a SMM is a slow relaxation of the magnetization at low temperatures accompanied by a magnetic hysteresis. The origin of SMM behaviour is the existence of an appreciable thermal barrier U for spin-reversal called magnetic anisotropy barrier which is related to the combination of a large total spin ground state (S(t)) and an easy-axis magnetic anisotropy. The extensive research on MnOAc and other SMMs has established more prerequisites for a rational development of new SMMs besides the high-spin ground state and the magnetic anisotropy: the symmetry should be at least C to minimize the quantum tunneling of the magnetization through the anisotropy barrier but lower than cubic to avoid the cancellation of the local anisotropies upon projection onto the spin ground state. Based on these prerequisites, we have designed the ligand triplesalen which combines the phloroglucinol bridging unit for high spin ground states by the spin-polarization mechanism with a salen-like ligand environment for single-site magnetic anisotropies by a strong tetragonal ligand field. The C symmetric, trinuclear complexes of the triplesalen ligand (talen(t-Bu))(6-) exhibit a strong ligand folding resulting in an overall bowl-shaped molecular structure. This ligand folding preorganizes the axial coordination sites of the metal salen subunits for the complementary binding of three facial nitrogen atoms of a hexacyanometallate unit. This leads to a high driving force for the formation of heptanuclear complexes (n+) by the assembly of three molecular building blocks. Attractive van der Waals interactions of the tert-butyl phenyl units of two triplesalen trinuclear building blocks increase the driving force. In this respect, we have been able to synthesize the isostructural series (3+), (3+), and (3+) with (3+) being a SMM. A detailed analysis and comparison of the magnetic properties of the three heptanuclear complexes and the tetranuclear half-unit (3+) provides significant insight for further optimization of the SMM properties. The modular assembly of the heptanuclear complexes from three molecular building blocks allows the fine-tuning of the molecular and steric properties of each building block without losing the driving force for the formation of the heptanuclear complexes. This possibility of rational improvements of our isostructural series is the main advantage of our supramolecular approach.
