Abstract

In this paper, we describe an experiment measuring low-$Q^2$ elastic electron-proton scattering using a newly developed cryogenic supersonic gas jet target in the A1 three-spectrometer facility at the Mainz Microtron. We measured the proton electric form factor within the four-momentum transfer range of $0.01\le Q^2 \le 0.045(\text{GeV/c})^2$. The experiment showed consistent results with the existing measurements. The data we collected demonstrated the feasibility of the gas jet target and the potential of future scattering experiments using high-resolution spectrometers with this gas jet target., Comment: 10 pages, 8 figures

Abstract

A cryogenic supersonic gas jet target was developed for the MAGIX experiment at the high-intensity electron accelerator MESA. It will be operated as an internal, windowless target in the energy-recovering recirculation arc of the accelerator with different target gases, e.g., hydrogen, deuterium, helium, oxygen, argon, or xenon. Detailed studies have been carried out at the existing A1 multi-spectrometer facility at the electron accelerator MAMI. This paper focuses on the developed handling procedures and diagnostic tools, and on the performance of the gas jet target under beam conditions. Considering the special features of this type of target, it proves to be well suited for a new generation of high-precision electron scattering experiments at high-intensity electron accelerators.

Abstract

The Mu3e experiment aims to find or exclude the lepton flavour violating decay $\mu \rightarrow eee$ at branching fractions above $10^{-16}$. A first phase of the experiment using an existing beamline at the Paul Scherrer Institute (PSI) is designed to reach a single event sensitivity of $2\cdot 10^{-15}$. We present an overview of all aspects of the technical design and expected performance of the phase~I Mu3e detector. The high rate of up to $10^{8}$ muon decays per second and the low momenta of the decay electrons and positrons pose a unique set of challenges, which we tackle using an ultra thin tracking detector based on high-voltage monolithic active pixel sensors combined with scintillating fibres and tiles for precise timing measurements., Comment: 117 pages. Minor corrections to the author list. Replaced with published version. Editor: Frank Meier Aeschbacher

7. Ethylzincation of Monosubstituted Alkenes Catalyzed by EtMgBr−Cl<INF>2</INF>ZrCp<INF>2</INF> and Palladium-Catalyzed Cross Coupling of the Resultant Diisoalkylzinc Derivatives

Author

Gagneur, S., Montchamp, J.-L., and Negishi, E.

Abstract

The reaction of monosubstituted alkenes with 0.5 molar equiv of Et2Zn in the presence of a catalyst generated in situ by treatment of Cl2ZrCp2 with 2 molar equiv of EtMgBr produces regioselectively the corresponding diisoalkylzincs 1, generally in high yields. Their direct cross coupling with a variety of organic halides in the same reaction vessel can be achieved in good yields with a catalytic amount of a palladium complex.
