It is composed of 300 water Cherenkov detectors (WCD). Each of them is a cylinder of 7.3 m in diameter and 4.5 m in height. POSTSUPERSCRIPT. They are equipped with 4 upward facing photomultiplier tubes (PMT), one 10” Hamamatsu R7081-HQE at the centre of the tank and three 8” R5912 halfway to the edges. 95%. Those two characteristics compensate the smaller instantaneous sensitivity compared to the imaging atmospheric Cherenkov technique, especially at the highest energies for which fluxes tend to be low. Around 10 TeV, the footprint on the ground produced by a gamma-ray shower is comparable to the size of the instrument. Therefore, most of the events triggering the instrument will fall outside the main array which makes the event reconstruction less accurate because of degeneracy between the core position and the energy of the shower. In order to improve the reconstruction of those events thus improving the instrument sensitivity, a sparse outrigger array of small tanks has been added around the main array.|Russia’s invasion of Ukraine is triggering a drop in stock prices. But now may not be the best time to go on a stock shopping spree. That's because prices may slide even further amid a heightened state of uncertainty, says Eric Freedman, the chief investment officer at U.S. On Tuesday, President Vladimir Putin got approval from lawmakers to use Russian troops outside of the country. This comes one day after Putin declared two Ukrainian regions independent. President Joe Biden said Putin’s moves represent “the beginning of a Russian invasion of Ukraine.” He also announced forthcoming sanctions targeting Russian financial institutions and sovereign debt that are set to go into effect on Wednesday. UKRAINE'S RIPPLE EFFECTS: Inflation is high and gas prices are rising. Russia's invasion of Ukraine could push them higher. USED CAR PRICES: You knew used car prices were high. Markets reacted. The Dow Jones Industrial Average shed nearly 483 points, or 1.4%, on Tuesday. While the S&P 500 and NASDAQ Composite also closed lower, by around 1% each. Fears are mounting that the Russia-Ukrainian conflict could escalate as the U.S. European allies respond to Russia. That would have more of a direct impact on U.S. But markets have largely priced in the risks of a Russian invasion of Ukraine and U.S. So if you’re looking for an opportunity to buy stocks that are falling in price, known as “buying the dip,” you may want to consider holding out. “The store will remain open for a couple of months,” Freedman told USA Today. “But if one is sitting on a bunch of cash, could you put a little bit to work here?
