Noise in the low energy channels of HPGE ?

I have two low background HPGe systems. I am noticing, very often, noise in the spectrum in the low energy side of the spectrum. The systems are powered by a good quality uninterrupted power supply system (UPS) with an isolation transformer. Ground to neutral voltage is always zero. The laboratory is always maintained at 22 degrees C. I do not know what would be the problem. Please, anybody, have any suggestions?

Energy minimization in LAMMPS using NVT ?

How do I do energy minimization in lammps with NVT ensemble ? I am using the following command and it does not seem to work. It stops at extremely high energy and gives me the error zero search...

Does anyone know HRM channel in a 2 plex QIAGEN Rotor- Gene Q qPCR can be used as a separate channel?

I am going to have 3 different probes in my qPCR work that I am going to do. But I realized that the machine we have in the lab is a Rotor-Gene Q 2plex HRM Platform, saying it has green, yellow,...

Why is the sum of the elements in a row in a Q matrix equal to zero?

When explaining substitution models, the substitutions are expressed as Q matrix. Why is the sum of the elements in a row zero?

Is it possible to have two luminescence bands of the same peak position but with different intensities in single spectrum??

Hi! If it is possible to have two luminescence bands of the same peak position in a spectrum, what is the reason behind formation of two separate bands instead of one? This phenomenon is related...

How can I find a Raman spectrum wavenumber corresponding to what compound?

I have several Raman spectra with very distinct peaks at certain wavenumbers, such as 277, 359, 466, 583, 623, 686, and 795cm-1. How can I identify them to what compound(s)? The RRUFF and others...

How the Ground Plane implantation is performed without damaging (and w/o varying the undoped nature) the top Si (8-10 nm) in FDSOI technology ?

It is a general practice to introduce Ground Plane in FDSOI devices under the BoX. The Ground Planes are introduced by Ion Implantation through Top Si layer and Buried Oxide. I wanted to know that...

Why the CHi^2 is close to zero with a bad fitting but the Rp and Rwp are still high?

I am refining my XRD data using in FullProf program. The intensity of the modulated X-ray peaks is almost flat. I tried to adjust the peak intensities but unsuccessful. What is the reason? I guess...

What are difference between laser diodes, simple light emitting diodes and power light emitting diodes when operated in the visible spectrum ?

I want to illuminate a scene (small space) using LED to capture photographs or videos of some tiny objects inside the space. But am not sure if I should use a Laser LED, or simple LED or power...

Can we use a compensation matrix with single staining that the negative population for each single staining is below zero?

Recently we used single staining to make a compensation matrix. But, for each single staining we saw that 13 to 25 percent of our negative population had been shown below Zero. In this situation...
