Research and development for the first batch of key equipment for the world’s most powerful electron collider, the Circular Electron Positron Collider (CEPC), in China, has made solid progress. Wang Yifang, director of the Institute of High Energy Physics (IHEP), under the Chinese Academy of Sciences in Beijing, who is also a deputy to the National People’s Congress, made the comments. The overall development of the CEPC project is moving forward smoothly, with some of the first batch of equipment reaching design standards.
Klystron is among the first batch of key equipment for the super-sized collider, which scored a 60 percent efficiency in the prototype test earlier this year, reaching world advanced levels, up from below 50 percent, according to Wang. Wang’s team aims to produce an even better version of the klystron with 80 percent efficiency this year. The location for the CEPC has yet to be determined, Wang noted.
The CEPC project will reportedly cost 35 billion yuan ($5.05 billion) and will have a circumference of 100 kilometers, with center-mass energy of up to 240 giga electron-volts, both setting a world record. Chinese scientists are eyeing the completion for CEPC construction by 2030.
The conceptual design for the CEPC passed international inspections in September 2019. Scientists from the US, Europe and Japan have participated in designing the project, and will work on the building process and conduct research with the collider.
The Large Hadron Collider, the Swiss project near Geneva, is currently the world’s largest and most powerful particle collider and reportedly the largest machine in the world. In a bid to maximize the project’s service life, scientists are mulling upgrading the electron positron collider in around 2040 into a proton collider, Wang noted. By then, the center-mass energy for the CEPC will have reached about 100 tera electron-volts, seven times as powerful as the Switzerland’s project, Wang said.
The outbreak of COVID-19 pandemic has brought risks of suspension and delay in implementing procurement contracts for some equipment for large-scale projects due to adjustments in budgeting plans. Wang suggested that legal entities engaged in major project construction should be allowed to raise funds through multiple channels or borrow other funds to ensure that construction tasks are completed on schedule.
Wang revealed that another IHEP project, the cosmic ray observation station on an area equivalent to 200 soccer fields in the wilderness of Daocheng, Southwest China’s Sichuan Province, 4,400 meters above sea level, has been affected by budget cuts.
The key area is around a spectacular 135 kilometer-long, 5-7 kilometer-wide lake, Pangong Tso. It’s in Ladakh, which is a de facto extension of the Tibetan plateau. One third is held by India and two thirds by China.
Mountain folds around the lake are called “fingers.” The Indians say Chinese troops are close to Finger Two – and blocking their movements. India claims territorial rights up to Finger 8, but its de facto holding extends only to Finger 4.
New Delhi has been steadily expanding infrastructure development – and also troop deployments – in Ladakh for nearly a decade. Units now spend longer periods deployed along the LAC than the six months that used to be the standard rotation.
These are called loop battalions: They do a back and forth with the Siachen glacier – which was the theatre of a localized India-Pakistan mini-war in 1999 .
The Indians maintain there are no fewer than 23 “disputed and sensitive” areas along the LAC, with at least 300 “transgressions” by PLA troops every year.
Crossing the line
The Indians are now particularly focused on the situation in the Galwan valley in Ladakh, which they maintain was breached to a distance of 3 to 4 km by PLA troops now in the process of digging defenses.
The current flare-up started building in late April, and led to a series of scuffles in early May, described as “aggressive behavior on both sides,” complete with fistfights and stone throwing. The Indian version is that Chinese troops crossed the Line of Actual Control (LAC), with vehicles and equipment, to block road construction by India.
5-23-20, 500 China’s new energy vehicles Aiways U5 were shipped to European Union where NEV originated.
The first 500 units exported to the EU are just the beginning of Aiways’s internationalization. This electric SUV that’s been given a three out of the full five-star crash rating by the European New Car Assessment Programme (EuroNCAP), it will have the ability to provide up to an estimated 500km of range and be able to accelerate from 0 to 100kph in 9.0 seconds before reaching a top speed of 150kph. The first deliveries planned in August and looks to be priced at an estimated 35,000 euros for Germany and The Netherlands, while it will cost just 28,000 euros for those in the UK.
The puddlers forcefully excreting liquid from the business-ends of their abdomens. When puddling, it is quite obvious that butterflies take in copious amounts of mineral-enriched fluids that they require for various biological functions. The biological processing of these fluids within the bodies of the butterflies to extract the requisite minerals must be extremely efficient. Once the minerals are absorbed, the remaining fluids are ejected from the butterfly’s body, so that there is no superfluous build-up of the excess fluids that the butterfly does not need.
China’s Long March 5B 長征五號B carrier rocket, carrying a new generation of manned spacecraft test vessel and a flexible inflatable cargo return module test capsule, ignited at 6:00 p.m. today 5-5-20 at Wenchang 文昌Space Launch Complex, and after about 488 seconds, the carrier and rocket were successfully separated and entered the scheduled orbit. It was reported that the flight as the first mission for the space station was successful, which kicked off the “third step” of China’s manned space program. The Long March 5B carrier rocket is based on the Long March 5, and is mainly responsible for major launch missions such as the China Space Station module. The Long March 5B carrier rocket is about 53.7 meters long, with a core diameter of 5 meters, four 3.35-meter diameter boosters bundled, a fairing length of 20.5 meters and a diameter of 5.2 meters, fueled with non-toxic and non-polluting liquid oxygen, liquid hydrogen and kerosene as propellants, a take-off mass of about 849 tons, and a NEO carrying capacity of more than 22 tons, making it the largest NEO carrier rocket in China.
China Manned Space Office said they have identified the reason of two recent launch failure which happened on March 16th and April 9th in 2020. Over the past month, model team and aerospace experts have carried out in-depth problem review, cause analysis, and test verification. The location and mechanism of the malfunction of the two failed missions have been determined. At the same time, a comprehensive quality rectification and review across the entire spaceflight is organized. Appropriate adjustments have been made to the rocket launch plan initially scheduled to be implemented soon.
