CP/CMS (Control Program/Cambridge Monitor System) is a discontinued time-sharing operating system of the late 60s and early 70s, known for its excellent performance and advanced features. It had three distinct versions:
CP-40/CMS, an important "one-off" research system that established the CP/CMS virtual machine architecture
CP-67/CMS, a reimplementation of CP-40/CMS for the IBM System/360-67, and the primary focus of this article
CP-370/CMS, a reimplementation of CP-67/CMS for the System/370 – never released as such, but became the foundation of IBM's VM/370 operating system, announced in 1972.Each implementation was a substantial redesign of its predecessor and an evolutionary step forward. CP-67/CMS was the first widely available virtual machine architecture. IBM pioneered this idea with its research systems M44/44X (which used partial virtualization) and CP-40 (which used full virtualization).
In addition to its role as the predecessor of the VM family, CP/CMS played an important role in the development of operating system (OS) theory, the design of IBM's System/370, the time-sharing industry, and the creation of a self-supporting user community that anticipated today's free software movement.
Hello! When I google about the CMS magnet I see that there is a 4 T magnet. However in the diagrams with muons, like this one, it seems to be another 2 T magnet beyond that. Where is that placed exactly. I assume it doesn't go around the whole detector, as that would affect the central region...
The Higgs boson couples to mass, muons are relatively light, that makes a decay to a pair of muons (muon+antimuon) very rare. In addition there are many other processes that produce pairs of muons, making this decay mode challenging to find. For a long time it was expected that the experiments...
In this picture of CMS, there is a huge gap between the two sides. There is no way that the collision occur directly in midair right?
So is the gap already been sealed? ( which means the picture was taken before it started to operate) Or I am completely wrong?
Hi, I'm undergraduate researcher and my professor is interested in the answer to this question. He's kind of left me in the dark on why this is important to us, but that is another matter.
We want hadrons that are produced at LHC conditions and decay before reaching the detector. So far all...
I was wondering what the differences are between CMS and ATLAS when it comes to their channels. I know they detect for the H →γγ, H → 4l, H → eνμν channels, but I was wondering how they differ in their detection for these channels.
I was also wondering if there were any noticeable...
I want to loading about 14 ton of CMS (Carbon Molecular Sieve) into a PSA Nitrogen Producer tank.
The tank is 5 meter tall with 2 m in diameter.
What is the best, simplest and fastest method to load the pellet of CMS into that big tank?
I consider this mortar screw pump and connect it...

CMS released their conference note a bit earlier. They see absolutely nothing at the mass range where the excess appeared in 2015.
It is a bit curious...
Any help about interprting the results of ## \sigma(pp \to H) \times BR (H \to WW) ## mentioned in Fig.(12-13) in [arXiv:1509.00389[hep-ex]]?
In that paper [arXiv:1512.06728v3[hep-ph]], page 8, its said that according to these figuers ## \sigma ( pp \to H \to WW^* )\leq 54, 37 fb...
The CMS or cosmological background permates the whole universe. It's mentioned so often in study halls and on documentaries that NOTHING can peak further back into the universe evolution beyond the CMS.
Just want to hear all of your ideas on how YOU would solve this problem if you were on this...
After a slow start, the LHC and its detectors worked nicely and collected a lot of data this year (~3.5/fb). While many analyses are still ongoing, both ATLAS and CMS will report several results on Tuesday 3 pm (CET)*. The presentations will probably appear here, a...
I found CMS total delivered luminosity from Cern Statistics website (22.98 inverse fb). But i want to calculate myself and using values from website's supertable page. (https://acc-stats.web.cern.ch/acc-stats/#lhc/overview-panel)
But my result is 8.16E+42
Where is my mistake?
I read one of the CMS results for new charged Higgs on :
I can't understand this sentence at the main results:
What does it mean? is that constrains the theoretical calculations of sigma(pp -> H+- tb) to be 0.41-0.030 pb...
Dear engineers and physicists,
I would like to ask you a question about Component Mode Synthesis (CMS), which is the topic of my bachelor thesis. My primary resource is the classical AIAA article "Coupling of Substructures for Dynamic Analyses: an Overview" by Prof. Craig.
For now I am...

Good Evening All!
Well... that registration was fun. I'm red/green colorblind (I guessed green and got it right!).
Anyways... I've got a problem (other than my color blindness).
My website, www.FireBellyLawnCare.com, is up and running. The designer... sadly... is out of contact. I would...
