The photon sieve is a diffractive optical element similar to a Fresnel zone plate, however instead of alternating rings of opaque and transmissive material the sieve is made up of many holes arranged in concentric circles. A sieve provides diffraction-limited resolution where traditional reflective and refractive optics are unable to, such as in the extreme ultraviolet. We present here recent results of testing the photon sieve's properties and comparing them to theory. Such results include multiple wavelengths, point spread function analysis, and off axis imaging. We also investigate the case in which there are multiple solar spectral lines near the sieve's depth of focus. The image observed will be a combination of multiple distinct spectral lines with different intrinsic blurs. Separating these lines is mathematically similar to an inverse problem we developed for slitless spectroscopy and is considered within this same framework.

Computational image formation with photon sieves for milli arcsecond solar imaging
Öktem, Sevinç Figen; Davila, Joseph (null; 2016-07-30)
A photon sieve is a modification of a Fresnel zone plate in which open zones are replaced by a large number of circular holes. This diffractive imaging element is specially suited to observations at UV and x-ray wavelengths where refractive lenses are not available due to strong absorption of materials, and reflective mirrors are difficult to manufacture with sufficient surface figure accuracy to achieve diffraction-limited resolution. On the other hand, photon sieves enable diffraction-limited imaging with...
Coherent J/psi photoproduction in ultra-peripheral PbPb collisions at root s(NN)=2.76 TeV with the CMS experiment
Khachatryan, V.; et. al. (Elsevier BV, 2017-09-01)
The cross section for coherent photoproduction accompanied by at least one neutron on one side of the interaction point and no neutron activity on the other side, , is measured with the CMS experiment in ultra-peripheral PbPb collisions at . The analysis is based on a data sample corresponding to an integrated luminosity of 159, collected during the 2011 PbPb run. The mesons are reconstructed in the dimuon decay channel, while neutrons are detected using zero degree calorimeters. The measured cross section ...
Optimization of a Convex Rail Design for Electromagnetic Launchers
Polat, Hakan; Tosun, Nail; Ceylan, Doga; Keysan, Ozan (Institute of Electrical and Electronics Engineers (IEEE), 2020-06-01)
A rail geometry with a convex cross section instead of a rectangular one provides a higher contact area, uniform current density, and less transition on the contact surface, and it increases the performance in electromagnetic launchers. In addition, the design of convex rails should be considered together with armature structure, the distance between rails, rail length, and parasitic masses that all have an influence on the overall efficiency and armature/rail transition. A novel complete rail and launch pa...

The Hamiltonian for an electron travelling through a large-amplitude backward electromagnetic wave, an axial guide magnetic field and radiation field is formulated. Poincare surface-of-section plots show that this Hamiltonian is non-integrable, and leads to chaotic trajectories. Equilibrium conditions are derived in the limit where the radiation field approaches zero. Compared to conventional FEL, the total energy of the system at pondermotive resonance E(c) is large, while the electron's critical energy...
Singularities of spectra of infrared reflection of tertiary compounds of the type T1BX2
Hasanlı, Nızamı; Khomutova, M.D.; Sardarly, R.M.; Tagorov, V.I. (Springer Science and Business Media LLC, 1977-07-01)
The frequencies of lattice vibrations are calculated for compounds of the type T1BX2 on the basis of the linear-chain model. The calculated frequencies are compared with experimental values for TlGaS2 and TlGaSe2. The good agreement between the calculated and experimental frequencies serves as proof of the applicability of the linear-chain model to compounds of the T1BX2 type. The proposed method of calculation of frequencies makes it possible to predict the theoretical frequencies of lattice vibrations of ...
