Abstract

Turkish Accelerator and Radiation Laboratory (TARLA) is a facility capable of accelerating an electron beam up to 40 MeV. Two beamlines were proposed to generate free-electron laser radiation and bremsstrahlung. The accelerator employs two normal conducting cavities, so-called buncher cavities: subharmonic buncher (SHB) and fundamental buncher (FB), and two cryomodules that house two TESLA cavities each. SHB operates in 260 MHz and FB in 1.3 GHz, and is powered by 1.5 kW and 500 W radio frequency (RF) amplifiers, respectively. Each TESLA cavity is driven by 18 kW saturated high- power solid-state amplifiers (SSA). In addition, a L band pulse compressor system is designed and implemented at the facility to actively promote high-power RF research. Currently, setup of a resonant ring test bench is approved to test the RF components under high power RF conditions. This paper describes the TARLA high power RF, RF controller, and network structures. High power tests and measurements of the RF components of the TARLA beamline are given. Outcomes from the operation of the L band pulse compressor are explained, and the resonant ring test stand is stated as a summary. Key words: radio frequency, high power, buncher cavity, amplifier, control system. Le Laboratoire Turc d'Acceleration et de Radiation (TARLA) est une facilite experimentale pour accelerer des electrons jusqu'a 40 MeV. Deux lignes de faisceau sont proposees pour generer de la radiation laser a electrons libres et de bremsstrahlung. L'accelerateur utilise deux cavites a conductivite normale, appelees cavites de regroupement, de regroupement sousharmonique (CSH) et de regroupement fondamental (CF) et deux modules cryogeniques logeant deux cavites TESLA chacun. CSH opere a 260 MHz et CF a 1.3 GHz, avec alimentation par amplificateurs radiofrequence (RF), respectivement de 1.5 kW et 500 W. Chaque cavite TESLA peut etre alimentee par amplificateur etat solide sature de 18 kW. De plus, un compresseur pulse en bande L a ete concu et construit sur place pour faciliter la recherche RF a haute puissance. Actuellement, un banc d'essai d'oscillateur en anneau resonant a ete approuve pour tester les composantes RF a haute puissance. Nous decrivons ici le contenu haute puissance RF de TESLA, le controleur RF (bas niveau) et les structures de reseau. Nous exposons les tests de puissance et les mesure des composants RF de la ligne de faisceau de TARLA. Nous expliquons les resultats d'operation du compresseur pulse en bande L et l'anneau resonant est mentionne dans le sommaire. [Traduit par la Redaction] Mots-cles: radiofrequence, haute puissance, cavite de regroupement, amplificateur, systeme de controle., Introduction The TARLA linear accelerator is mainly based on an injector line including thermionic gun, subharmonic and fundamental bunchers, and two superconducting cryomodules (SC modules), each housing two TESLA RF [...]

Abstract

Melatonin (N-acetyl-5-methoxytryptamine) is a neurohormone that maintains circadian rhythms.sup.1 by synchronization to environmental cues and is involved in diverse physiological processes.sup.2 such as the regulation of blood pressure and core body temperature, oncogenesis, and immune function.sup.3. Melatonin is formed in the pineal gland in a light-regulated manner.sup.4 by enzymatic conversion from 5-hydroxytryptamine (5-HT or serotonin), and modulates sleep and wakefulness.sup.5 by activating two high-affinity G-protein-coupled receptors, type 1A (MT.sub.1) and type 1B (MT.sub.2).sup.3,6. Shift work, travel, and ubiquitous artificial lighting can disrupt natural circadian rhythms; as a result, sleep disorders affect a substantial population in modern society and pose a considerable economic burden.sup.7. Over-the-counter melatonin is widely used to alleviate jet lag and as a safer alternative to benzodiazepines and other sleeping aids.sup.8,9, and is one of the most popular supplements in the United States.sup.10. Here, we present high-resolution room-temperature X-ray free electron laser (XFEL) structures of MT.sub.1 in complex with four agonists: the insomnia drug ramelteon.sup.11, two melatonin analogues, and the mixed melatonin-serotonin antidepressant agomelatine.sup.12,13. The structure of MT.sub.2 is described in an accompanying paper.sup.14. Although the MT.sub.1 and 5-HT receptors have similar endogenous ligands, and agomelatine acts on both receptors, the receptors differ markedly in the structure and composition of their ligand pockets; in MT.sub.1, access to the ligand pocket is tightly sealed from solvent by extracellular loop 2, leaving only a narrow channel between transmembrane helices IV and V that connects it to the lipid bilayer. The binding site is extremely compact, and ligands interact with MT.sub.1 mainly by strong aromatic stacking with Phe179 and auxiliary hydrogen bonds with Asn162 and Gln181. Our structures provide an unexpected example of atypical ligand entry for a non-lipid receptor, lay the molecular foundation of ligand recognition by melatonin receptors, and will facilitate the design of future tool compounds and therapeutic agents, while their comparison to 5-HT receptors yields insights into the evolution and polypharmacology of G-protein-coupled receptors. The MT.sub.1 melatonin receptor differs markedly from 5-HT receptors and shows atypical ligand entry; its structure with various ligands sheds light on receptor specificity., Author(s): Benjamin Stauch [sup.1] [sup.2] , Linda C. Johansson [sup.1] [sup.2] , John D. McCorvy [sup.4] [sup.15] , Nilkanth Patel [sup.1] [sup.3] , Gye Won Han [sup.1] [sup.2] , Xi-Ping [...]
